I would like to export the audio from a quicktime movie. i have QT 7 Pro. I want to listen to the audio from the movie in my car, on a CD. I tried it a few different ways, as AIFF, another, and it saves a large file but doesn't sound when I play it. No sound. Is there a way to save it so it's audible? These are AVI files. Thanks so much for any help.
