I would strongly recommend *against* using movie-specific config
files, since there is absolutely no way to override the settings in
them. They take precedence over the command line, which is really
stupid... :( Instead for stuff like this, I've just been putting a
text file on the CD with instructions to the user on how to play the
file correctly...
