Hi,
  Have you recently updated the NetPBM package on your system?
>From the messages you included below, it looks to me like the 'ppmtompeg'
video encoder terminated early. (there should have been lots of informational
video encoder messages printed to the console)
I'd suggest checking checking if your 'ppmtompeg' is working correctly or not
and then try again. You can tell the VMD movie plugin not to delete the
movie frames when it's done, and then you can try re-running the video
encoder on the frames by manually running ppmtompeg with the .par file
that the movie maker created:
  ppmtompeg /tmp/plug_sim_an15_500_mid.par
