Alright. I want to make a backup of my dvd. I used a dvd ripping software to rip the dvd files to my hd. I don't want to compress any of the files, so i thought i would only burn 4 of the .vob files, using nero. Nero transcoded the first one great, but the 2,3, & 4th .vob files have no audio. How do I burn the .vob files using nero without loosing audio?
