Please advice, thank you.

Hi :slight_smile:

I’ll try and tackle a couple of questions. First, I tend to scan at 4x on my LH-20A1H, as 8x tends to give wacky results (and also jitter is less wacky at 4x). This applies to all DVDs I scan, regardless of burn/rated speed.

Your Litey is a 1ECC scanner, so:

PI Errors = “acceptable” max is 280
PIF errors = “acceptable” max is 4

Jitter is really a matter of personal prefewrence and you’ll get varying answers to this one. If I get jitter below 10% average or max then I’m happy.

POFs, well Liteys don’t report those anyway :wink:

As for the Quality Score, I don’t take much notice of it (prefer to look at the scans), but someone else may help you there.

Edit: Hehe, obviously I would pick the LiteOn to scan with :wink:
