Well, I have encoded 500 gigs worth of movie backups in a few weeks, and haven't done any a-b'ing yet. I am about to purchase an ATV. Now that my drive is full, and I am taking a breather until I get another, I have been comparing screen shots, and EVERY ONE is at least 30%darker than the original. I mean I am no videophile, but there are things that you JUST CAN'T SEE! So I feel screwed, and I can't believe there aren't more people freaking about this. I never upggraded to 3, and am using the stock ATV setting. HELLLLPPPPP. I've spend weeks and months encoding. ARRHGGGH!
