I created a movie in a program on one of my Mac Pro's, with Big Endian audio (no choice on the codec used). When I sent it to my other Mac Pro for compression, it wouldn't play the sound. When I re-exported the original movie through Quicktime with AAC audio it played without issue. Both computers are on the same version of QT. Please let me know if I should post this in a different forum, I didn't see a QT forum and it is an audio issue. Any thoughts of a fix I need to do on Mac Pro #2 to get this to work? Thanks.
