I don't know what your video hardware is, but my TNT2 Vanta with the
Nvidia proprietary driver doesn't seem to support brightness and
contrast at all. I just get error messages on stdout when I use 3 and 4,
so I use "-vop eq2", which doesn't seem to add too much CPU time. Since
your interactive controls work, you may have a different problem.
