KProbe/PlexTools Scans - Page 1

In the following screenshots you can see the PI/PIF scans for the DVD-R media we burned with the LaCie d2 DL drive. The software we used for all measurements is KProbe v2.2.3, 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 only PIF errors, despite what KProbe reports. In addition, all discs have been scanned with PX-712SA v1.03 using PlexTools v2.15 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 speeds, since when the 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

The PI/PIF scans show that the LaCie d2 DL drive performed well with the DVD-R media used. NEC drives have a reputation of being very good quality recorders, and the LaCie d2 DL drive further confirms this. Very good quality burns, especially with TY, Verbatim and CMC media, but with some small exceptions, as with MAM media.

There are no Plextools scans for BenQ and Optodisc media. The Plextor 712SA recorder could not recognise these discs because of firmware limitations/bugs (firmware version 1.03).
