I used DVDDecrypter to rip a chapter I wanted. When playing back this ripped file using PowerDVD I have audio. I used VirtualDubMod to edit down the chapter to just the scene I wanted and convert it to AVI. It asked me which audio stream I wanted and I selected the appropriate English audio stream. After playing back the completed file, however, there was no audio at all. Any ideas on what might have gone wrong? Thanks in advance.
