Rob,

Perhaps we are speaking different languages (we generally don't), but the 
way I read your statement, I have to disagree strongly. MPEG-1 and MPEG-2 
are fully self-contained and media independent streams that can be 
transmitted in real time, but which can also be stored in memory as one big 
file with its own format, e.g. for playback at any time. I know MPEG-4 also 
has a file format, probably with a lot more functionality, but still you 
can consider MPEG-1 and MPEG-2 streams as being a simple file format. Which 
may not meet all MPEG-4 requirements of course.

Kind regards,

Jan van der Meer

MPEG does not specify file formats for MPEG-1 and MPEG-2.
There will be a file format for MPEG-4 that does this right.
