I have another patch... This is an attempt to support the use of BUP
files. A bit hacky.
But if it gets the job done, then maybe it can work. Please try. This
patch may not
work just because it is buggy. I haven't had a chance to try it. So if
it just fails
outright, feel free to instead apply the second patch and see what you get.

If anyone wants to review the patch and throw rotten eggs my way, feel
free. I especially
want to know what mplayer, vlc and handbrake devs think of BUP files
and their usage.
