I have a dvd of boxing matches. The dvd (not copyprotected) consists of a few VOB files. Each VOB file may hold more than 1 fight or parts of a few fights. For example, one VOB file(#1) is of a fight from round 1 to the middle of round 4. The next VOB file(#2) is from the middle of round 4 of that same fight to the end. This VOB file(#2) also contains rounds 1 to 3 of a different fight. What I want to do is edit the second VOB file(#2) so that it only consists of the middle of round 4 to the end of the fight. I then want to join VOB file #1 and #2 to have the whole fight in one VOB file. I can easily put the VOB files onto my hard drive, but whenever I try to convert the VOB files into MPEG format, it looses the audio. Can someone tell me what to do in order to accomplish my goal? Am I correct by wanting to convert to MPEG?
