FYI, I took a look at your files.

The MP3 and MPEG Transport Stream files stream OK.  (Note, though, that 
QuickTime Player cannot play these streams - blame Apple :-)

Your MPEG Program Stream file turns out to have been very badly encoded:
1/ Each 'Video Sequence Header' is preceded by an (often large) sequence of 
zero bytes - in violation of the MPEG specs.  This was confusing the 
LIVE.COM MPEG parsing code.  I have now installed a new version 
(2004.08.17) that better handles files like this.
2/ Several of your video frames contain an unusually large number of MPEG 
'slices', each with the same vertical position.  Although this may not 
violate the MPEG specification, it is very unusual, and produces large 
numbers of very small RTP packets (and thus inefficient network bandwidth 
usage) when such a file is streamed.

If you try using a different MPEG Program Stream file - one that has been 
encoded properly - you should get better results.
