Both the 812S US0Q and 832S VS0J have problems with Optodisc OR8 media, but unfortunately I only have a screen capture of the 832S. I did get the 832S to init properly onto this media as well now, it seems the drive wouldn't function consistently on an ASUS P2B board, latest BIOS with a P3-600. The 812S results are even worse than these ones with triple the PIE rate, higher jitter, and about a 25% increase in the PIF rate. Quality score is 82 vs this posting of the 832S. My BenQ, Pioneer and LG drives burn this media with a PIE rate under 3 and usually a PIF rate under 0.05, jitter from below 8% to a max of around 10%. My PX-716A doesn't handle this media all that well either, but the quality score has never been below 92 until these Liteons. The results with a TS-H552U US06 were also under 10 for PIE rate, around 1 for PIF rate, jitter around 9% and qscore of 92.
