MP3 is MPEG1 Layer 3 (That's the audio layer). An MP3 is an MPEG1 file
without the picture info.

MPEG2 is the current standard used on DVD's and on DBS systems (The DBS
systems tweak MPEG2 for their own purposes, but they only send to their
decoders,so...)

The next iteration of MPEG is MPEG4 which is meant for multimedia purposes.
MPEG4 is based in large part on QuickTime. MPEG3 was skipped over due to the
name confusion possibilities.

There was MPEG3 development in progress, but it was abandoned when MPEG2 was
chosen for DVD (and HDTV and DTV, more importantly) and development shifted
to multimedia.

There are currently competing MPEG2 audio "standards" from Sony and
Phillips....(here we go again....).
