models, the XJ-HD163 and the XJ-HD165H. We will compare the three drives
in an attempt to find out if the newer model has any improvements over its
and in general see how it
performs under our usual suite of tests.

DVDInfoPro gives us some additional details about the drive's
capabilities as well:

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.
Lastly, let's see what additional information KProbe software returns for LiteON based drives:
- The package
retail box includes the internal drive, one audio cable for the internal connection
to the sound card, mounting screws, quick installation guide and
with PowerDVD 5 Software, Manual and DOS driver.
On the front, there is the DVD-ROM
and the compact disc logos located on the tray. The phone jack, sound level
control and the activity led are located on the left side and below the disc
tray. On the right side there
On the rear panel you can see the analogue and digital outputs (SPDIF), the
and the power input.
The drive is a half-height internal device,
much shorter than the usual CD/DVD recorder, making mounting in small form-factor
PC cases an easy task.
Below you can see a picture of the drive with noticeably smaller dimensions
compared with the older 163 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
