Your tests on this burn seem to show a difference among drives used to read the burn, is that right?
The test with the iHAS524 looks very uniform, but the read with the DW1655 is irregular, and the PIE increases with reading radius. That would show a difference in the drives? Or is there still some media effect? You are using the same media here for your tests, it appears (MCC 004 (000))
But increasing error rate on the DW1655 doesn’t seem to hold across all your tests. So I’m wondering how you tease out the difference between the burn/media quality and the drive itself.

I use scans of the same disc read in different drives to get an overall view of the burn quality. BenQ drives seem to be the least forgiving while drives using MediaTek chipsets (Lite-On and Samsung) give the lowest error rates, with Plextor Sanyo drives generally falling somewhere inbetween. But as long as all scans show error rates well within the specs, it gets a “pass” from me. If just one drive shows lots of errors, you can chalk that up to the individual drive just not liking that particular disc.
