I'm using Squeeze 5 to compress a .mov file to burn onto a dvd. I've selected DVD_PAL_16x9_Sm and for some reason it breaks up the file into two parts m2v and m2a. The m2v file no longer contains the audio. Do I have to re-combine the m2v and m2a files before burning it onto a dvd? Isn't there a way to compress a .mov file so that the audio and video remain combined?
