It seems like it has trouble reading what it has burned. With cheap media (ProdiscS03 burned at 4x) it aborts with read or seek arror around 3.8-4GB mark. Wth TYG02 (burned at 8x) that shows great PIF/PO scans it finishes transfer rate test but it will not go above 8x read speed and the curve is jagged, not smooth. All of the media has great transfer rate curves on the LiteOn DVD-ROM reader (model 165 I think) and on the Plextor 715A.
Is that a norm or is my drive a little bit on the shabby side?
