So I'm backing up DVD's on DVD Shrink 3.2 and about 75% of the time I get sound but no voice. Strange because often I'll get an alternate track, like french, or director comments, but never the original voice for the film. Sometimes I'm able to back up and it works perfectly, but this happens more often than not. I'm manually backing it up to my hard drive and burning with Nero 8 on a Vista 64-bit Ultimate system. Any solutions?
