I open this thread because of a discussion I had on another forum concerning DVD quality scanning.
It suddenly striked me that I've seen on this forum many scans performed with NEC or BENQ drives showing PI errors levels up to 3000+.
But theorically, from all available sources I could find, PI errors should max at 1664 when scanning @8ECC... which is the case for Benq and Nec.
So something's wrong, either these drives are reporting very badly, or this 1664 calculation is flawed, anyway there's a missing piece and I feel a bit lost.
I've re-read ECMA 338 and 337 but couldn't find this missing piece.
Does anyone have some light to shed on the subject?
