I doubt if its an error with the movie file itself.  The guy has a problem trying to copy the file over to his smc. 
These are possible solutions:
1)  Try formatting your smc, reinstalling the moviepark, and then copying over the movie file
or
2)  While transferring the large file, just wait.  Every 3 megs or so, the copy hangs for a moment.  So just be patient.
