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.
If your using dvd shrink, then you can right click on the preview window, and go through the audio streams there, and decide which ones you need and which ones you dont.
