More info on this.  The audio is not missing when played in mplayer but not 
usre why:

- playing the MPG file in Windows Media Player is missing the video
- playing the MPG file in mplayer (i.e. mplayer.exe test.mpg) does produce 
audio.  Here is the output of the play command of this MPG file:

$ mplayer.exe test.mpg
