Optorite DD1205 Dual DVD±RW Recorder - Page 15

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 SOHD-167T with "9S14 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 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 (6X CAV for KProbe, 2X CLV for PlexTools).

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.

• Pressed movie

• DVD+R9 Media @ 2.4X

Traxdata 2.4X @ 2.4X

Verbatim 2.4X @ 2.4X

- Summary

The DVD recording quality with Double Layer media is very good, approaching that of pressed discs. Both Verbatim and Traxdata media reported low levels for PIE/PIF. However, the discs were not playable on our standalone players since there was not bitsetting option.
