Doesn't ECMA state that error counts should be carried out at 1x (like AudioDev does IIRC) ?
Exactly. And also, measuring equipment should be properly calibrated as well. That is why Kprobe's PI/PO should be taken with grain of salt.
I don't know why people making a big deal about PIPO/C1C2 anyway. Of course, i do kprobe some, only couple first when switch brand of discs or backing up crucial data. That's because it is just easier than getting up to the DVD player and watch the whole thing. Or for DATA, i just kprobe for data verification. If i'm gonna spend 15 minutes, i'd rather kprobe the discs. At least, the graph just looks more cool.
One thing though, people will say low error discs last longer. I don't really agree that it is necessary true. It's more about how stable the chemical on discs are, how well is coating, thing like that. If the media is actually rotten chemically, so much error will occur on the disc thus no amount of error correction can help.
So stop scanning every single disc and get over number of PI/PO, it does not matter. As long as your DVD works as you want, you'd fine.:bigsmile:
