I have ripped some episodal dvd's which i no longer have in my posession. Using dvddecrypter i have ripped each dvd into one giant m2v file along with 2 ac3 audio tracks (different languages). I have got a hold of a dub of these dvd's in another language which i would like to add to the dvd except the audio's are split into one file per episode. My problem and question is, what is the easiest way to join and sync these separate audios to the video to make one track? Making menus and adding the third track is not my problem. Only thing i can think of is to import the audio files into something like audacity and manually do all the spacing.
