[slimpickins]

hi, i have aload of dvd's to abck-up, around7gig each, is dvd-rb with cce2-pass gona be better than the rest, i use 1 click copy pro, which claims to be very good, it uses ac3 transcoder?whatever that is, what ive noticed is dvd-rb has a much more mellow picture with the colors a little faded but tiny details better displayed and 1click has more fuller colors but a tinyy bit scratchy
how long does dvd-rb cce 2pases take

twice as long. As the name suggests, it is a 2 pass process. Personally, I think it is worth it for lareger files that need to be reduced. Other will use Shrink to shrink 50% and say they cant tell the difference between it and the original. Your call on time versus quality versus what you can see.
