hi i have a VOB file which i am working on joining to another (thats not a problem). My problem is that one VOB has the 5.1 audio on 0x80 ID and the other VOB has it on 0X81. What can i do to make sure the final DVD i create will use the 0x80. In essence what I am trying to do is fool the VOB in to thinking the stream exists at 0x80 instead of 81. I've tried ifoedit, vobedit etc. demux, remuxed etc. maybe I'm just missing a vital step somewhere. please help. I need to get this video out soon. (it's a compilation of homemade school videos.
