I'm not sure, but I believe that this error message refers to the size of the
MPEG movie frames. We've also run into problems with MPEGs running fine on
Unix machines but having problems on Windows machines. What I've been given to
understand is that some of the Windows players, particularly those from
Microsoft, assumed that the MPEGs would be restricted to the standard TV
resolution. You might try making smaller movies, and see if those play okay.
