Memorex D² DVD±RW/DL Recorder - Page 16

In the following screenshots you can see the PI/PIF scans for the DVD+R/RW media we burned with the Memorex F16. The software we used for all measurements is KProbe v2.2.3 and the reader was 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 can only report PIF errors and not PO, 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.

- Summary

Inspite of the poor writing quality with the previous media types, the Memorex F16 is very good with DL media. Both samples revealed excellent writing quality.
