I know this is a lame-ass thing to post about but sorry, im psyched that i finally got it all to work, haha.
I copied the movie National Treasure and am copying The Exorcist: The Beginning right now. Actually Ive made one other copy of Lamb of God's Killadelphia, but that was on 2 discs, which sucks ... so tonight was really my first successful dual layer copy.
I have a NEC 3520AW burner and I used dvdfab-decrypter and nero 6.something.
Couldnt have done it without you guys here in this forum tho cuz i had no clue about dvdfab before that ... so thanks for the help all. later.
