Hello. After I thought I got the hang of back-ups I ran into another problem. I used DVD Shrink re-authoring part to just include the main movie. I made sure the audio settings were on the default, AC3 English ones. I previewed it and it played the movie and sounds just fine. After encoding, I tried playing the VOB files in my Power DVD program. They play just fine, nothing bad at all. I burned to dvd and put in my home dvd player. The video is fine, however, the dvd commentary is playing in the background. When this same dvd is played on my pc, I do not hear the dvd commentary. Is there way to make sure this doesnt happen? I don't know why I hear the commentary on my stand alone player but not my PC dvd-rom.
