So if you do a second audio, does that mux to the same avi or a seperate one. Becasue if you muxed english as audio 1, and German as audio 2, it would just garble together right? Or once you mux them with the movie can you choose which language you want? Or does it mux them seperate, or maybe not at all? That second audio track has always been confusing to me? And yes you are right english is my mother language so i have had no need to use other languages, but I figured if I was french or German or whatever, I would just mux that language in with the movie, if it was offered on the DVD. Where am I going wrong here?
