I ripped a movie with DVD Shrink and then used ConvertXtodvd to burn to disc (all to remove region protection so can play the movie on some limited players). In convertxtodvd the audio comes up as "0", so there is no sound once the disc is burned. No other movie/disc has done this using this process. I've never encountered this problem before. Can anyone tell me why this has happened? Is it a new way of protecting the copying of discs perhaps?
