MP4 is the container format for the MPEG4 standard (specifically part 
14), and is based off the QuickTime container format.  It is completely 
independent of MPG, which is the container format for the old MPEG and 
MPEG2 standards.  The reason the above works is because any properly 
designed media player outright disregards the extension, and instead 
reads the 'magic number' in the first couple bytes of the file to 
determine what format it is in.
