Is there a way with Nero or some other program that lets me preview Audio tracks so I can determine what to keep and/or delete? Specifically, I'd like to delete stuff like DTS tracks, commentaries, foreign language dubbing, etc.. etc.. I see lots of audio tracks on my DVDs, but I can't tell which ones are vital for the movie and which ones are excess fluff. All I want are the 5.1 and 2.0 tracks, but I am afraid to delete everything else not knowing what they are for. There's no sense in having Audio Tracks for Videos that I removed - if you get my gist.
