TEAC DV-W512G Dual DVD±RW Recorder - Page 14

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.

- Summary

With specific media, the PI/PIF error rates were low, but with others very high...
