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 NEC ND-2510A. The software we used for all measurements is the 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 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 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.

• Maxell 8X DVD-R @ 8X

• MCC 4X DVD-R @ 8X

• Promedia 8X DVD-R @ 8X

• That's 4X DVD-R @ 8X

• TY 8X DVD-R @ 8X

• Verbatim 8X DVD-R @ 8X

- Summary

The PI/PIF scans shows that the NEC ND-2510A performed well with the used DVD-R media, except for the Promedia 8X disc.
