Hi Margaret,
  Can you tell me which version of the netpbm software you have
installed? I found that some of the older versions are buggy,
so you may have to have a newer version if the old one fails to
work for you. I'm not sure that's your problem, but its a
possibility if everything except for the last phase of the
movie compression is working correctly. Do you get any errors
in your VMD console window, or in any Tk dialog boxes? Let me know
if you see any other indications of the source of the problem.

Thanks,
  John Stone
