Optorite DD1205 Dual DVD±RW Recorder - Page 16

In the following screenshots you can see the PI/PIF scans for the DVD-R/RW media we burned with the Optorite DD1205. 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 PIF errors, despite what KProbe reports. In addition, all discs have been scanned with PX-712A v1.04 using PlexTools v2.16 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, 2~5X CAV for PlexTools). It's interesting to see the disc scanned at low & high speed, since when the error rate increases at a specific disc region, 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 writng quality with rewritable media is rather good. Both Kprobe and Plextools reported PI/PIF levels below the limit. For one more time all the discs were playable on our standalone players.
