I tried again with totem in Hoary.  And I made sure it was using the xine 
backend.  Totem sees the video track as a iso mpeg-4 (ffmpeg), and the audio 
track as an acc (libfadd) with a bitrate of 0kbps, and the then only display 
the video, not the audio track.

As I wrote in another email, vlc from Hoary's universe works perfectly on that 
mp4 file.  And looking at the property menu in vlc, it sees the video as a 
mp4v, the audio as mp4a, but this time with a bitrate of 705kb/s and a sample 
rate of 22 khz.

Anyway, thanks for everyone for your help.  And its great to finally be able 
to watch these videos from Ubuntu using only applications available in main 
and universe.
