KProbe/PlexTools Scans - Page 6

In the following screenshots you can see the PI/PIF scans for the burned DVD±R media . The software we used for all measurements is KProbe v2.2.5, 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. In addition, all discs have been scanned with the PX-712A (v1.04 firmware) using PlexTools v2.16 for comparison levels.

Comparing the KProbe and 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.

8X DVD+R Writing Speed

• BeALL 8X DVD+R @ 8X

• BenQ 8X DVD+R @ 12X

• Intenso 8X DVD+R @ 8X

• Optodisc 8X DVD+R @ 8X

• Philips 8X DVD+R @ 8X

- Summary

The drive performed very well with specific media (Intenso, Optodisc and Philips) and badly with BeALL and BenQ media.
