LiteON SOHW-832S Dual DVD±RW Recorder -
Page 1
LiteOn,
as a leading optical storage manufacturer, announced at the end of April, a
new 8X DUAL burner, the "SOHW-832S". The main difference
with the presently available SOHW-812S series was the adoption
of Double Layer (DVD+R DL)
recording.
Our main interest is to see how the new LiteON drive compared with the previous
812S series and most importantly, if and how DL writing works. Another important
issue would be writing quality and the various subtests where the LiteOn 812S
performed very well. So, let's get cracking!
- New Features
The most important new feature of the SOHW-832S is the ability to read/write
Double Layer DVD+R media.
The
Double Layer DVD+R system uses two thin embedded organic dye films for data
storage separated by a spacer layer. Heating with a focused
laser beam irreversibly modifies the physical and chemical structure of each
layer such that the modified areas have different optical properties to those
of their unmodified surroundings. This causes a variation in reflectivity as
the disc rotates to provide a read-out signal as with commercially pressed read-only
discs. Below is a picture showing the structure of a DVD+R DL media.
For more information about DVD+R DL technology, you can visit the DVD+RW
Alliance website or
Philips Research website.
The LiteOn SOHW-832S also supports:
- SMART-BURN avoiding Buffer UnderRun Error, Automatically adjusting writing strategy & running OPC to provide the best burning quality
- SMART-X function adjusts CD-DA / VCD / DVD data extraction
to the fastest allowable speed according to both data request rate from
host and disk quality
- VAS® system reduce vibration and noise during recording and reading
In
terms of writing/reading speeds, the drive supports 8X (Z-CLV)
writing for both DVD±R and 4X (CLV) writing for DVD±RW
formats, while it can read DVD-ROM (pressed) up to 12X (CAV). The drive offers
40X (P-CAV) / 24X (Z-CLV) / 40X (CAV) specs for the CD formats.
The drive's model name, SOHW-832S, is coded according to the SONY Alliance
Models ODD Naming Rule:
- S: SONY
- O: Optical
- H: Half-Height Optical Loader
- W: DVDRW ODD Type

The specs don't indicate whether the drive supports Mount
Rainier for either of CD or DVD formats, but we will check this later. The
drive also uses the RPC II region control, allowing a user to change the drive's
region
at most 5 times, which however can easily be bypassed with various utilities.
Below are the drive's main specs as given by NeroInfoTool and DVDInfoPro:
Lastly, let's see what additional information KProbe software returns for
LiteON based drives:
- European Retail package
The
European retail package includes the LiteOn SOHW-832S, a quick install guide,
mounting screws and a sound cable. While the retail box doesn't mention
it, it supports 1-year warranty for Europe, Middle-East and Africa. Included
software is Nero v6 OEM version and CyberLink PowerDVD v5.0 retail
version. The total cost is expected to be around €135.00.
The package also contains one LiteON 8X brand DVD+R media (RICOH, ID Code:
RICOHJPNR02) and a LiteOn 4X brand DVD-R (CMC Magnetics, IDCode CMC MAG. AF1)
.
Our retail package included a DVD+R DL (from Mitsubishi Chemicals) media,
but we suspect that this won't be included with most retail packages that users
buy...
Now let's take a look at the drive itself.
The SOHW-832S looks more or less the same as the previous 812S series
and it has all the appropriate logos indicating the supported formats. The
busy indicator lights up green when the device is active, orange when reading
/ accessing a disc and red when burning. On the front, the user will distinguish
the DVD+R DL logo!
On the rear panel you can see the analogue and digital outputs (SPDIF), the
IDE connector
and the power input. Our drive was manufactured during May 2004 in Taiwan.
Something that should be noted is that the drive is much shorter than the
usual CD/DVD recorder, making its mount an easy task even for PCs with small
cases.
Below you can see a picture of the drive with noticeably smaller dimensions
compared with the Plextor Premium drive.
Removing the screws and opening the drive's cover voids the drive's warranty.
For reference reasons, we post the following pictures. You can click on the mainboard
picture for a higher resolution image:
The LiteOn SOHW-832S further incorporates (located on
the underside of the controller circuit board), a high-speed
DVD dual Optical Disk Controller chipset from MediaTek Inc. consisting of
two CMOS ultra-scale integrated circuits, the MT1816E and MT1818E. The MT1816E
is the front-end analog signal processor and the MT1818E is the servo control
and Endec IC. The pickup system is the Sanyo SF-DB 10SA. Note
that the LiteOn SOHW-812S used the exact same board design (with slight differences
in memory brand used but at the same memory timings)!
- Installation
The drive was installed as secondary master and under WindowsXP recognized
as a "LITE-ON DVDR SOHW-832S". The drive arrived
with firmware vVS01 and till today there hasn't been a newer firmware release.
Below is a picture from Nero Burning Rom, showing the drive's specs.
After all tests had finished, LiteON released a newer firmware, VS03 with the update description "match more media".
Nothing really changed in the drive's properties, except the firmware revision.
Notice that the drive is already one month old, and for
beta testers there is already available a newer revision, VS05, which according
to Lite-On, greatly improves writing quality:
We will compare the drive with its older brother, the SOHW-812S, and the
Plextor PX-708A, since all three drives have exactly the same DVD/CD recording
specs.
- Testing software
In order to perform our tests we used:
- Nero CD-DVD Speed v3.00
- CDVD Benchmark v1.21
- ExactAudioCopy v0.9 beta5
- Nero Info Tool v2.21
- KProbe v2.1.0 (Reader: LiteOn LDW-811S firmware vHS0Q, Reading speed 8X CAV)
- PlexTools v2.13 (Reader: Plextor PX-712A firmware v1.01, Reading speed 8X CLV for CD-R)
- DVDInfoPro v2.54
- LiteOn Booktype Utility v1.0.6
- Nero Burning Rom v6.3.1.10
2. Transfer Rate Reading Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 2
Transfer Rate Reading Tests
- CD Format
The LiteOn SOHW-832S supports up to 40X reading speed. Below are the transfer
rate graphs, along with the comparison with the other two drives:
As we can see from our tests, the drive seems slightly faster
than its predecessor with Mode1 Pressed disc and Mode1 CD-R media. The seek
times are also lower than the 812S drive (click on its graph to view these).
The
832S
has
the same
maximum speed for US-RW media, only 32X.
- DVD Format
As was expected, the SOHW-832S is faster than the 812S, even if by a difference
of only 0.4X, with SL (Single Layer) DVD-ROM media.
The two layers of a PTP DVD-ROM disc are read sequentially with the drive
starting reading from the inner part of the disc, which is the beginning of
each layer, towards the outer range, for each layer. The 832S was again faster
than the 812S by 0.5X
The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks toward the inner part of the disc. The average reading speed is 6.26X (again 3~8X CAV).
Again, the SOHW-832S is slightly faster compared to the 812S.
The only problem came with DVD-RW media, since the drive dropped its reading
speed
at
the end resulting in a lower average rate.
Since both the 812S/832S have the same reading speed (8X CAV) for DVD-Video
discs, the ripping performance was more or less the same.

3. CD Error Correction Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 3
CD Error Correction Tests
In the following tests we check the drive's behavior when it comes to reading
scratched / defected discs. The test discs we use are the ABEX series
from ALMEDIO.

The 832S drive performed very well with the ABEX TCD-721R. The drive's
highest spike was at -36.0 dB(A) and the total score of 76.8 points is very
good. We
must also note that C2 accuracy reached 99.7%, an almost perfect score. The
total error count is also relatively low.

- CD-Check Audio Test Disc
The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction
/ Error correction capabilities of a CD player. The disc offers a signal combination
with disc error patterns to rate the drive's abilities to read music and reproduce
it completely. Five tracks on the disc contain a sequence of progressively
difficult tests. These tracks are referred as Check Level-1 through Check Level-5.
The
files are reproduced (played) through a software multimedia player (i.e.
Windows Media Player). Each level is considered as passed, if the tone coming
out
from the speakers is smooth, continuous without interruptions, skipping or
looping. The higher the Check Level passed, the more reliable the sound reproduction
of the tested device.

The performance of the LiteON SOHW-832S was good with a final average score

did not produce valid results. We don't know if this was a problem with the
software or of the produced
data.
4. DVD Error Correction Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 4
DVD Error Correction
Tests
In the following tests we examined the DVD reading capabilities of
the 832S drive with scratched / defected
DVD media.
For the tests we used CDVD Benchmark and Nero CDSpeed . The reference test
media
come
from
ALMEDIO.
- Single Layer media
ABEX TDR-821
This is a single sided, single layer DVD-ROM with a 4.7GB capacity, and its
surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm.
The following transfer rate picture comes from the CDVD Benchmark v1.21 transfer
rate test.
The LiteOn SOHW-832S read the disc at 12X CAV and the scratched area did
not affect the process. The disc was read accurately and no read errors
were
reported.
The performance reveals high error correction capabilities with scratched single
layer DVD-ROM discs.
ABEX TDR-825
This is also a single sided, single layer DVD-ROM of a 4.7GB capacity. The
data structure of the disc is exactly the same as that of the TDR-821, with
the difference that there are no scratches on it but defected areas of dimensions
ranging from 0.5 to 1.1 mm. There are also fingerprints sized between 65 and
75 micrometers.
As in the previous test, the disc was read without any "read errors".
There was a small drop in reading speed just before the fingerprint
defective area, but the test was finished successfully.
- Dual Layer media
ABEX TDR-841
This is a 8.5GB dual layer, single sided DVD-ROM disc with artificial scratches
of dimensions ranging from 0.4 to 3.0mm, in both layers.
The drive didn't have any major problems as the above graph shows.
ABEX TDR-845
The disc is a single sided, dual layer DVD-ROM disc of a capacity of 8.5GB.
The only difference between the TDR-845 and the TDR-841 is that the first includes
defected areas and fingerprints. The dimensions of the defected areas range
from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micro meters.
Here we notice the same behavior as with the single layer disc. When the
drive enters the fingerprint defective area, it drops reading speed for a while
but quickly regains speed and finishes the test without any problems.
ABEX TDV-541
The TDV-541 is a single sided, dual layer DVD-VIDEO disc, with a capacity
of 8.5GB.The disc is based upon the TDV-540 series which is designed for inspection
and adjustment of DVD-VIDEO players. The discs check the layer switch operation
from layer 0 to layer 1 and also include test pictures and test signals for
DVD sound files. The current TDV-541 checks also the error correcting capabilities
of the drive and includes scratches from 0.4 to 3.0 mm.
The reading process started at 3.54X and reached 8.47X at the 4.0GB point,
where the drive changed layer and reduced its reading speed till the end. No
serious problems were noticed, very small glitches but the result is good.
ABEX TDV-545
The
TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer
DVD-VIDEO disc with a capacity of 8.5GB. The TDV-545 includes artificial black
dots on the data surface, sized from 0.4 to 1.0 mm. It has also 65 - 75 micro
meters fingerprints.
Black dots and fingerprints on the disc's surface did not create any reading
problems, and the drive finished the task successfully.
5. Protected Disc Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 5
Protected Disc
Tests
- Reading Tests
To create the image of the various protected titles to the hard disk, we
used Alcohol 120% software and the appropriate settings, according to the protection
type of the inserted discs. Below you can see the duration of each process
as well as the transfer rate in each case, which should prove interesting
for all users.

The 832S drive performed almost equal with the 812S drive. Unfortunately,
it cannot skip read errors quickly, giving a high reading time for a SafeDisc2
protected
disc.
- Writing Tests
The LiteON SOHW-832S supports the DAO-RAW writing mode. For checking the drive's EFM correction status, we used 3 different game titles with different SafeDisc 2 versions having the latest software patches installed. After making the images of the various titles onto the hard disk, we burned them (maximum speed) with Alcohol 120% v1.9.2.1705. Two different discs were created for each title; one with the "Bypass EFM error" enabled and one more with the function disabled.
- Fifa 2004 - Safe Disc v3.1x
- The Sims Superstar - Safe Disc v2.9x
- The Sims Unleashed - Safe Disc v2.8x
- Serious Sam Second Encounter - Safe Disc v2.51.021
- Max Payne - Safe Disc v2.51.020
The table below shows the results of the attempted backups and whether they worked (game installed / played normally), or not.

6. DAE Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 6
DAE Tests
- Pressed and CDR AudioCD
The LiteOn SOHW-832S supports up to 40X CAV DAE speed. When using a pressed
AudioCD and its CD-R copy, with EAC, we logged the following results:
The 812S was slight faster than the 832S with the test discs. Such performance
differences can be improved with future firmware upgrades. As EAC reports,
the drive caches DAE, supports accurate stream and can report C2 error information.
- Advanced DAE Quality
The LiteOn SOHW-832S received a score of 100 (perfect) in the Nero CD Speed
Advanced DAE test. CDSpeed showed that the average reading speed is 27.84X,
and
that
the drive supports reading of
SubChannel
data. Leadin / Leadout data and CD
Text.
- Reading 90/ 99mins AudioCDs
7. Protected AudioCD Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 7
Protected AudioCDs
For the test procedure we used three audio discs with different audio copy protections. The ripping process performed for all protected Audio discs performed with Exact Audio Copy v0.9beta5.
The tested protected Audio discs were:
- Sony's Key2Audio from "Celine Dion - New Day Has Come"
- Cactus Data Shield 200 from "Natalie Imbruglia - White Lilies Island"
The Cactus Data Shield 200, contains artificial errors that are not easy to bypassed from the reader, while the Key2Audio contains a second session, causing problems to readers when try to read the Table Of Contents (TOC).
The tested tasks are:
- Recognition of the inserted disc (Yes/No)
- Ripping all wavs (with EAC's Burst Mode) to the hard disk with copy&compare function.
- Listening to the produced wavs for any click/skips.
The LiteON SOHW-832S recognized up to the 12th Audio track of CDS200 disc,
and with the "Retrieve Native TOC" option removed the 13th Data track.
The test results are shown at the following table:
|
Key2Audio |
CDS200 |
LiteOn SOHW-832S |
Ripping process completed, EAC reports
no problems, Read&Test CRC comparison successful for all tracks |
Ripping process completed, EAC reports timing problems, Read&Test CRC comparison not the same for all tracks |
The LiteOn SOHW-832S will rip both Key2Audio/CDS200
protected audio discs. Both discs were recognized and their contents were
ripped
at the maximum speed. However, the drive may not rip 100% accurately, the
CD200 discs since EAC reported timing problems and at the same time, Read&Test
CRC check comparison was not the same for all tracks. No problems were
noticed with Key2Audio discs.
- Cactus Data Shield 200.0.4 - 3.0 build 16a (Aiko Katsukino - The Love Letter)
This
is a "special" CDS200 build, since it doesn't contain any artificial
errors during the ripping process. Most problems occur then trying to write
the ripped wav files, since the produced CD-R disc contains C2 and CU errors!
This "problem" is rumored to be connected with specific
chipset weaknesses..
We ripped the disc contents with EAC and burned the produced wav with the latest Nero version as AudioCD+CD-Text. The burned media was checked for C1/C2 errors with PlexTools/KProbe software using Plextor PX-712A (firmware v1.01) and LiteOn LDW-811S (firmware vHS0Q).

CDS 200.0.4 - 3.0 build 16a |
LiteOn SOHW-832S |
Reading performed without any errors, writing produces few C2 spikes |
- C1C2 Error rate from PleXWriter PX-712A (8X CLV reading speed)
- C1C2 Error Rate from LiteON LDW-811S (32X CAV reading speed)
- C1C2 Error Rate from LiteON LDW-832S (32X CAV reading speed)
- BETA/Jitter Error rate from PleXWriter PX-712A
The C1/C2 error graphs indicate that the drive didn't manage to produce
a 100% error free disc.
Lets try to extract all wav files with the Plextor PX-712A and PlexTool DAE Error Correction 5th Level enabled:
No errors were reported after extracting all files, despite the high spike
PlexTools reported C2 around 40minutes. The drive's error correction mechanism
corrected
the errors.
8. CD Recording Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 8
CD Recording Tests
The LiteOn SOHW-832S supports 40X CD-R and 24X US-RW recording speeds.
The drive
supports 8X, 16X (CLV), 24X, 32X and 40X (P-CAV) writing speeds. Below are
the recording speeds as detected by Nero Burning Rom.
It's quite possible that due to the Smart-Burn system, the maximum burning
speed was reduced down to 32X or even 24X (for example Mam 48X SG Ultra). The
user can disable Smart-Burn and get the maximum writing speed. This can be
done
under
Nero Burning Rom->Choose Recorder->Options->Un-tick Smart-Burn Enabled.
Another utility that can be used to check the maximum speed of the inserted media comes from LiteON with the name
"SMART-BURN Media Check Program", a very useful utility for LiteON users:
According to Nero CDSpeed, the drive reached the maximum 40X speed. The test
started at 18.47X and finished at 41.72X having an average speed of 31.57X.
Click on the image below to see the whole graph.
For the burning tests we created an 80min data compilation through Nero Burning
Rom, recording the data on a 700MB disc. The LiteON SOHW-832S finished the
task in
3:16 minutes, for the maximum 40X writing speed, one second
faster than the 812S model.
The
writing performance varies according to the inserted media, as our tests
showed. The SmartBurn system will lower the writing speed if the media ID code
is not found in the drive's firmware. Below is a chart demonstrating
all recording times with various media.
The best performance came from Mam 80min 52X media with 196secs (3:16mins)
with SmartBurn disabled, since when enabled, it allowed only 24X for the specific
disc. The highest recording time comes from TraxData 80min 52X media
with 201secs (3:21mins).

The SOHW-832S supports the 16X CLV, 24X Z-CLV rewriting speeds, with Ultra Speed Rewritable Media
(US-RW). The drive also writes at 4X CLV with NS CD-RW and 10X CLV with HS-RW
discs.
Below you can see the Nero CD-DVD Speed writing simulation test with blank
24X US-RW media from Mitsubishi Chemicals.
The drive starts the writing task at 16.00X and reaches the maximum 24X
at the 14:00 min address mark on the disc. According to CDSpeed, the average
writing speed is 22.57X.
We also used Nero Burning Rom in order to burn a data disc with 24X US-RW
media from MCC. The data compilation we burned had a size of 651 MB and the
duration of the recording process was 4:07 minutes.
- CD-RW Mount Rainier Tests
We used Philips Mount Rainier Validation Suite v2.2 to test the drive's
compliance with the Mount Rainier format. All three scripts loaded in the Validation
Suite (mandatory command set, Light R'n'R and Heavy R'n'R) but for some reason
the Mount Rainier Suite didn't work as it is supposed too.
9. CD Writing Quality - 3T Jitter Tests
LiteON SOHW-832S Dual DVD±RW Recorder - Page 9
3T Jitter Tests
In the following page you can
see the 3T
Pit & Land Jitter graphs using various media burned at 48X CAV writing speed.
- 3T Pit results
Generally the drive didn't perform satisfactorily with most media used.
The highest 3T Pit jitter reached 43nsec, which is way above the Red Book
limit
(35nsec).
The best results came with Mam 52X CD-R media.
- 3T Land results
The average 3T Land results were also high. The maximum 3T Land Jitter
reached 49nsec and again, Mam 52X CD-R media produced the best results.
In the following page we check the C1 and C2 error rates of the same discs,
to come up with more specific conclusions.
10. CD Writing Quality - C1 / C2 Error Measurements
LiteON SOHW-832S Dual DVD±RW Recorder - Page 10
C1 / C2 Error Measurements
We measured the C1 / C2 error rate on the recorded discs we burned at the
various supported writing speeds. The software we used is PleXTools Professional

- Summary
The LiteOn SOHW-832S needs to improve its writing quality with CD-R media.
With specific media we noticed high C1 and more importantly, C2 errors, while
with one disc (Intenso 80min) the produced disc was completely un-recognizable
by
the Plextor drive. We also noticed that Mam 52X media was burned at
40X with SmartBurn disabled, but the produced disc was very good.

LiteON SOHW-832S Dual DVD±RW Recorder - Page 11
DVD Recording Tests
- Writing Performance
The LiteOn SOHW-832S supports
DVD-R/RW and DVD+R/RW writing. The maximum supported speed for the DVD±R
is
8X (6X~8 Z-CLV) and 4X CLV for DVD±RW
media. Nero Burning Rom reported speeds, are shown below. Notice that the drive
burns CLV at 4X & 6X writing speeds for both DVD±R
formats.
By using Codeguys "Speedhacking
Tool Pack for LiteOn DVD Writers", we were able to see which media codes
are supported for the ±R/RW formats and at which recording speeds (for
VS03 firmware):
- 8X DVD+R
- AML 002
- BeAll000 P80
- CMC MAG E01
- DAXON AZ2

It is possible that with the Codeguys "Speedhacking
Tool Pack", a user can change the maximum recording speeds for lower
rated media and burn them at 8X or 6X. However this must be used
with caution!
By using Nero CD-DVD Speed's "create disc" function with Plextor's
4X DVD+R media, we are able to see the 8X Z-CLV recording technology being
used by the SOHW-832S recorder.
The drive starts writing at 3.96X until 0.1GB where it shifts up to 6X,
until 1.2GB where it further shifts to 8X and stays there till the end. The
average writing speed is around 7.14X. This recording strategy is used
for both
DVD±R
formats.
- Burning Tests
We burned 4315MB of data on various DVD±R, DVD±RW media.
We used the maximum allowed writing speed for each disc, with the SmartBurn
feature enabled. The best recording times for the DVD-R format came from Maxell's
8X media with 9:19mins. However, the drive didn't perform very well with
That's 8X DVD-R and CMC 8X DVD-R media, aborting with "Illegal Disc" write
error inside Nero. Also, no 4X media was allowed to burn at 8X. Certainly,
the 832S needs to be improved with future firmware upgrades.
With DVD+R media, we didn't see any write errors, but a rather strict supported
media list for the 8X writing speed. The lowest burning time came from Plextor's
4X DVD+R media (based on TY) with 8:38mins, followed by Traxdata 8X DVD+R
with 8:58mins. It's rather strange that we see such high time variations between
the
various media burned at 8X. This could be explained, since the drive kept dropping
writing speed at the end of the disc.
Below are all the burning results with the various media types used.

- DVD Overburning Tests
In order to test the drive's DVD overburning capabilities, we used two media
types, one from Traxdata 4X DVD-R and one from Plextor's 8X DVD+R. As you can
see, the drive refused to start the test with DVD-R media,
while with DVD+R, the test started but when it reached 4.38GB, stopped with
an error message.
Therefore, LiteON SOHW-832S cannot overburn with either DVD±R formats.
- DVD+MRW Tests
We used MRW Validation Suite 2.2 by Philips to test the compliance of the
drive with the Mount Rainier DVD+MRW format. For the test
we used 4X DVD+RW media from TraxData and 2.4X DVD+RW media from Sentinel.
The test was terminated immediately after starting prompting us to insert a
blank
DVD+RW
disc. We have seen the same behavior with other drives also and probably when
a newer version is released, we will update our review.
12. KProbe/PlexTools Scans - Page 1
LiteON SOHW-832S Dual DVD±RW Recorder - Page 12
KProbe/PlexTools Scans - Page 1
In the following screenshots you can see the PI/PIF scans for the DVD+R/RW
media we burned with the LiteOn SOHW-832S. The software we used for all measurements
is the KProbe v2.1.0, and the reader is the LiteOn LDW-811S with "HS0Q
patched" firmware, being able to read DVD±R/RW media up to 8X CAV.
All scans have been performed at 8X with PI/PIF Sum8. Note that LiteOn drives
cannot report PO but PIF errors, despite what KProbe reports. In addition,
all discs have been scanned with PX-712A v1.01 using PlexTools v2.13 for comparison
levels.
Comparing the KProbe/PlexTools scans we can see major differences in the
reported PI/PIF error rates. The main explanation is that we have two different
readers, with different pickup/chipset combinations, scanning at different
reading speeds (8X CAV for KProbe, 2X CLV for PlexTools). It's interesting
to see the
disc scanned at low & high speed, since when error rate increases at a
specific disc area, it should appear in both scans...else it would be, perhaps,
a reading glitch of the tested reader.
Note: PI/PIF errors only give us a quick look at the error
rate of the burned media. Those scans should be taken not as the absolute criteria
of the burning quality but as an indication level.

- Summary
Judging from the PI/PIF scans we can say that the LiteON SOHW-832S performed
well with the used DVD+R/+RW media. There are specific cases where the
error rate was high and POF errors occurred, but this was a single occasion
with
Traxdata 4X DVD+RW media.

- Summary
The SOHW-832S is quite unstable with DVD-R, since it "managed" to
produce 2 beer coasters at 8X while not reaching very good quality
with the rest of the burned media. Certainly, this issue should be
looked at by LiteON
engineers
and fixed in the near future with upcoming firmware upgrades.

14. DVD+R DL Tests - Page 1
LiteON SOHW-832S Dual DVD±RW Recorder - Page 14
DVD+R DL - Page 1
The main difference between the LiteOn 812S and 832S is the adoption of the DVD+R DL format.
By using Codeguys "Speedhacking
Tool Pack for LiteOn DVD Writers", we were able to see that, currently
(VS03 firmware), only Mitsubishi Chemicals and Ricoh's DVD+R DL media ID codes
are supported for DVD+R DL writing :
For our tests we used the media sent by LiteON for our tests, based on Mitsubishi
Chemicals with the following information, as reported from DVDInfoPro software:
- DVD+R DL BookType Setting
We used the latest version (1.06) of LiteON's Booktype Utility. The drive
was recognized without any problems, we had already inserted a DVD+R DL media:
We tried changing the booktype from DVD+R DL to DVD-ROM
The utility informed us that the Booktype was changed:
however, after re-checking the drive's status we saw that the BookType setting
was still DVD+R DL:
Things succeeded after using KProbe's Bitsetting utility:
- Writing Tests
We burned two DVD+R DL discs with DVD-Video content and different BookType
settings. As the source we used "Gladiator Movie - Special Edition" disc1
with total size of 6.86GB. First we transferred the movie to HDD with DVD Decrypter
at ISO format (single file). Afterwards, we used CopyToDVD v3.0.0.16. The friendly
wizard welcomed us and from here we can select our main tasks:
For our test, we used the "Movie & Pictures" option, and then
the "Write DVD Video".
The software prompts us to select Video_TS/ISO image folder. We chose
the "GLADIATOR.ISO" image
and we selected the LiteON SOHW-832S burner.
After pressing"OK", the burning procedure started, however with
an unexpected delay of 50secs (disc recognized 57:01,
burning started 57:51) (DVD+R DL BookType):
and finished after 38:33 minutes. The average speed was
2.28X as reported from CopyToDVD software.
After changing the BookType setting we burned another DVD+R DL media (again
from Mitsubishi Chemicals) with CopyToDVD software, with however the newer
VS03 firmware revision. The burning process, again, delayed 1:28mins,
by the time CopyToDVD requested to start burning until the drive actually started
writing:
and finished after 38:36 mins. The average speed was 2.28X as reported from CopyToDVD software.
For comparison, we post some burning results from other DL writers,
which all burned the same content ("Gladiator Movie - Special Edition" disc1),
using CopyToDVD software:

- Writing Quality
In order to test the LiteON SOHW-832S DVD+R DL writing quality, we used not
our usual readers (LiteOn LDW-811S/Plextor PX-712A) since both didn't recognize
the burned disc, but the LiteON SOHD-167T DVD-ROM.
- DVD+R DL (DVD+R BookType)
Using KProbe v2.1.0 we got a rather good scan. Notice that the disc is not read at 3~8 CAV, but at 2.5X~5X CAV (DVD+R DL media).
Using Nero CD-DVD Speed and the LiteOn SOHW-832S we didn't notice any major
issues with the burned DVD+R DL media. The drive started reading at 2.39X,
reached 5.40X at the layer change producing a 4.09X average reading speed.
- DVD+R DL (DVD-ROM BookType)
Using the Plextor PX-712A and PlexTools we were able to scan the DVD+R
DL media with DVD-ROM booktype:
The reported PI error rate reached the 280 limit and the Nero CD-DVD Speed
is far from being perfect. Using the LiteON SOHW-167T at 6X reading speed,
and KProbe v2.1.0 we saw a much higher error rate than PlexTools reported,
of course the PI error trend line looks the same, however the CDSpeed graph
looks better than Plextor's PX-712A, even with some glitches:
- Compatibility Matrix
For our compatibility tests, we used the two burned DVD+R DL discs with DVD-Video content ("Gladiator Movie - Special Edition" Disc1) and PowerDVD v5.0.
We moved front and back around the layer change to ensure that the movie
can be playback without any glitches or skips. The results are shown below:

Its is clearly shown that the DVD-ROM booktype setting has a great impact
(70.37% instead of 29.63%) on DVD+R DL compatibility with either PC DVD
or desktop DVD players. There have been cases where even with the DVD-ROM
booktype, the disc wasn't recognized, but for this we shouldn't blame the LiteON
drive.

832S vs. SA300 - Page 1
For checking exactly what the SOHW-832S reports, we used different media,
burned by other recorders. These three media have been measured from the
well known AudioDev SA300 DVD CATS system at 1X.
Since all LiteON drives report only PI/PIF errors, we will compare those
measurements at various reading speeds:
- 3~8X CAV
- 2~6X CAV
- 4X CLV
- 1X CLV
Please note that the posted results are only valid for the specific tested SOHW-832S drive. Using other 832S drives can produce totally different results. Be aware!
#1st Test Disc - PISum8/PIF Comparison - 8X Reading speed
The PIF error rate trend line looks like the SA300, however with totally different
value levels.
#1st Test Disc - PISum8/PIF Comparison - 6X Reading speed
#1st Test Disc - PISum8/PIF Comparison - 4X Reading speed
With this test disc, all reading speeds 8X, 6X, 4X showed that at the end of the disc, the PI/PIF error rate increases. The SA300 system also measured similar performance. Its rather interesting that the 4X reading speed gave the "worst" results with the same trend line for PI/PIF errors but with higher values than the 8X speed...

Since all LiteON drives reports only PI/PIF errors, we will compare those measurements at three reading speeds:
Please note that the posted results are only valid for the specific tested SOHW-832S drive. Using other 832S drives can produce totally different results. Be aware!
#2nd Test Disc - PISum8/PIF Comparison - 8X Reading speed
We can see that at the 8X reading speed, the error trend line rises up at
the end. This is also what the SA300 series showed, of course not at the
same level. The PIF error trend line as reported by 832S shows the same
behavior
as the SA300 system. This time, values are quite close...
#2nd Test Disc - PISum8/PIF Comparison - 6X Reading speed
Using the SOHW-832S as a reader at 6X is not recommended. Why? Simply because
the reported PI/PIF error levels are too low, leading the viewer to judge
that the disc is at top shape, which isn't the case.
#2nd Test Disc - PISum8/PIF Comparison - 4X Reading speed
The 4X reading speed gave almost too perfect a result. Again, not recommended.

For checking exactly what the SOHW-832S reports, we used different media,
burned by other recorders. Three media were measured using the well
known AudioDev SA300 DVD CATS system at 1X.
Since all LiteON drives report only PI/PIF errors, we will compare those
measurements at three reading speeds:
Please note that the posted results are only valid for the specific tested SOHW-832S drive. Using other 832S drives can produce totally different results. Be aware!
#3rd Test Disc - PISum8/PIF Comparison - 8X Reading speed
At the 8X reading speed, the drive reported a rather close PI/PIF error trend line to what SA300 system measured. Of course the values are not the same but we can say it was a good performance.
#3rd Test Disc - PISum8/PIF Comparison - 6X Reading speed
The 6X reading speed is not recommended, since the reported PI/PIF error rate(s)
gives the viewer the impression that the disc is at perfect condition...
#3rd Test Disc - PISum8/PIF Comparison - 4X Reading speed
The 4X reading speed is not recommended, since the reported PI/PIF error rate(s)
gives the viewer the impression that the disc is at perfect condition...

832S vs. SA300 - Page 4
For checking exactly what the SOHW-832S reports, we used different media,
burned by other recorders. Those three media have been measured using
the well known AudioDev SA300 DVD CATS system at 1X. Since all LiteON drives
report
only PI/PIF errors, we will compare those measurements at one reading speed
(max). The disc actually read from 2.4X~5.5CAV. We didn't use KProbe v2.1.0
for the scan since all the times we tried, stuck at 50%, with ASPI/SPTI
layer.
Please note that the posted results are only valid for the specific tested SOHW-832S drive. Using other 832S drives can produce totally different results. Be aware!
#4th Test Disc - PISum8/PIF Comparison - MAX Reading speed
The SOHW-832S certainly cannot be used for scanning DVD+R DL media
since it reports much higher error rate than what SA300 series actually measured.
Note
that
sometimes the drive starts reporting up to 1000 constant rate PI
errors, not a good sign in our opinion.
20. BookType Setting Feature
LiteON SOHW-832S Dual DVD±RW Recorder - Page 20
BookType Setting
The LiteOn SOHW-832S supports BookType Setting for DVD-R/+RW formats. User
must set the BookType setting before burning any project.
There are two ways of setting the Booktype setting, either from:
This utility is available for free download at LiteON website.
The user can query the current Booktype:
Select other BookType (for example DVD-ROM):
And change the BookType to DVD-ROM, which offers higher compatibility with DVD Players.
Under Tools->Bitsetting, the user can view the current Disc Type and change
the BookType to either DVD-ROM/DVD+R/+RW. Unfortunately, Bit Setting isn't
supported for DVD-R media
Lets now try changing the Bit Setting for a DVD+R media, the current Booktype
is normal (DVD+R)
After pressing the "Set" button, the booktype changed to DVD-ROM
21. Conclusion

Conclusion
The LiteON SOHW-832S is the first ever LiteON recorder that supports DVD+R
DL writing. The new format has been highly awaited from many users as an alternative
medium for storage, mostly movies with 1:1 process. For this use, the LiteON
SOHW-832S is very good. DVD+R DL writing worked like a charm and when the initial
media prices drop, many users will enjoy it.
Listing the negatives, the drive's biggest problem is its initial firmware.
Explaining our previous comment, we saw that the writing performance with DVD-R
format is not what we might expect from LiteON. The drive produced two coasters
with 8X branded DVD-R media and generally the writing quality was below par.
LiteON of course has the policy of releasing frequent firmware upgrades but
we would
like the drive to be better fine tuned for the DVD-R format, since many users
don't even know what a firmware upgrade is...
Also, the supported media list for the -R format at 8X is not that high,
again newer firmware is expected to improve this situation. In case a user
uses LiteON's
Booktype for DVD+R DL, they will be disappointed, since it didn't work as
we expected it too, however by using KProbe you will get the desired results.
Lastly, something
annoying is that the retail package doesn't include a blank DVD+R DL media.
On the positive side, as usual LiteON's drive prices are a strong point
compared with the competition. The drive has very good CD/DVD error correction,
can backup SD2 2.8x builds and has no problem with protected Audio discs. A
big plus for the drive, is the fact that LiteON's unofficial community offers
many "unique" features/utilities (KProbe, Media speedhacks, RPC1
utilities, overclocking, etc...).
As a last word we we list the positive/negative points of the drive. We hope that LiteON will fix many of the reported problems and make us change our opinion about the drive ;-)
