It's all about moderation.
PIE's all below 200 (which would be the 350 limit on any other reader).
PIF's mostly below 10, and not huge clusters of them.
POF=0 of course.
Data integrity, not listed, should be 0 errors.
Disc A's error coding doesn't match, so it could have a data error. Was that a CMC? Disc B should play back with a few little pauses (maybe plays perfectly--depends on player), but no freezes or macroblocks. Is it a -R economy disc?
Anyway, players best tolerate PIE's, and when scanning with a BenQ, you can have PIE's up in the 200's (means 300's on most other readers) and the disc will play just fine. In fact, 90 for PIE's is a "centerline" tolerance. With such high PIE levels, jitter/write speed becomes more important to eliminate choppy playback.
