	Such a mode is possible in a few ways. Try simply stuffing MP3 audio in 
the QuickTime container along with ISO MPEG-4 video. In this case, the 
fourcc will be either 'ms' + 0x0055 (CBR) or '.mp3' (VBR). The QT/MP4 
file format also supports general MPEG audio inside the MP4 container. 
This audio can be MP3 as well as AAC (layers 1 and 2 are probably 
supported as well).
