I have used DVD Shrink and DVD Decrypter. Ripped DVD movie to iso file. I can play this back (using Daemon to mount it as a virtual disk) in Windows Media Player but there is no sound. I can play it fine using VLC media player. I used DVD Decrypter to burn the iso file to a DVD. It plays fine with VLC, plays with no sound in WMP and my DVD player can't play it at all. Where am I going wrong?
