Is there an utility which can do PI/PIF scannings (like those with LiteOn's) for the Pioneer DVR-108 ?
Yes. DVDInfoPro allows for it...check your PM. I am pretty sure with some tweaks, CDSpeed also allows for it.
Hum, I really would know if those tweaks exist for the Pioneer!! I am using DVDInfoPro with my Pioneer and find the result not consistents (different results testing the same media).
You ignore the fact that by definition, scanning with this drive will produce inconsistent results. It was never MEANT to be used as a reliable PI/PO scanner.......we just made it so!
