In order to play MP4 files, you must have MP4 Splitter installed. Not to be confused with MPEG-4 Video, the MP4 Bitstream format is a wrapper format (similar to AVI/OGM/Matroska).
The format was licensed from Apple's QuickTime by the MPEG group as the official file format for MPEG-4 content. It should become more popular as commercial entities start shipping more MPEG-4 content.
