I had problems with the media bundled with my 811S (way to go LiteON...) I have heard reports from a review site that they had the same problems with bundled media (which is likely a bad batch).
Ever sine I've bought new brands, and ANY brands I use even the best ones have extremely high PI/PO (note I booktype them to DVD-ROM).
I use Mxell DVD+R RICOHPNR01 and get PI's in the thousands! (scanned at 4x ECC 8) and PO values in the hundreds. Using Memorex, same crap, using tayo yuden same bloody crap no matter what media, the FUNNY thing is that when I run nero scandisc, all blocks are GREEN, not a single yellow (damaged sector) and the disc plays fine on my standalone DVD Player from start to finish without a skip, pause or anything, perfect playback I've also done a BIT for bit binary compare on the written DVD vs. the original DVD, and they came out IDENTICAL. So the moral of the story is, I could always make a backup to a new media should I ever run into problems, given the data is intact and fully readable
I know this will sound weird and I'm puzzled as to why my 811 gives very higih PI/PO readings, and yet the discs are perfect
Taking the disc on another LiteON produces similar high readings as well - I guess it's definately a LiteON issue and poor writing strategy, and the robust error correction kicking in ? At any rate, the high error rate has nothing to do with longevity of the media, given what I use is good quality media, so as long as all the data can be readable 100% I'm fine with it
The Kprobe scan reading starts off decent, no POs, and starting PI is usually within 10-15. Then towards the middle will start to climb gradually in the 100's, until it reaches the end over 400-500 and POs in the 100's. Yet the disc plays fine in my DVD Player and when it arrives at that spot the movie keeps playing smoothly, no skip, no pauses, (APEX AD1200). I also hear the APEX is picky about media.
On some disc my PIs are litteraly in the thousands. I've never burnt one ***g disc within the PI/PO specs PI<280 and PO<32, and I've never had one coaster or one disc fail on me. Talk about freaky sh LOL!
