i'm getting this problem with alot of my movies i try to watch and i don't get any sound because of it. i just got this program in a dvd drive and i don't want to have to get the new version of nero cause they want 80 $ for it.
have you tried dvd shrink (free) and/or dvd decrypter (free but make sure you only get that one from software section at top of page), to do ripping/encoding, then use Nero only for burning to dvd ?
it's not just nero they dont work in. i've tried windows media player, cyberlink power dvd, and some shit dvd player software i got with my dvd writer. but i know they work in nero because my friend has the same problem and them he got the nero dvd video plug in.
