As I said, Apple's QuickTime file format is the basis for the MPEG-4 file format. Without Apple and QUickTIme, we would probably be using the MS format. http://en.wikipedia.org/wiki/QuickTime#QuickTime_and_MPEG-4 QuickTime and MPEG-4 On February 11, 1998 the ISO approved the QuickTime file format as the basis of the MPEG-4 Part 14 (.mp4) container standard. Supporters of the move noted that QuickTime provided a good "life-cycle" format, well suited to capture, editing, archiving, distribution, and playback (as opposed to the simple file-as-stream approach of MPEG-1 and MPEG-2, which does not mesh well with editing)...
