[Mp4-tech] supporting AMR, AAC audios and MPEG-4 videos in QTfile format.

[Jean-Claude Dufourd]

.mov are Apple-private. MPEG does not know what is in a .mov, so this 
reflector is not the proper place to ask.
.mp4 are in the scope of this reflector (.3gp not really, but well...)
The information about MP4 file format is ISO/IEC 14496-12 and -14, 
available from www.iso.ch
Best regards
