One sure way to do brightness and contrast adjustment is to load the
soft equalizer filter (-vop eq2) on the command line, or however
that's done in the gui, then use the 1/2/3/4 keys to adjust. However,
if your computer isn't very fast this might make it too slow to watch
hi-res movies. A better solution would be to figure out why the
hardware equalizer controls don't work.

In order for us to help more, we need to know at least what video card
you're using, and hopefully which drivers you're using as well. Also,
the output of the "xvinfo" program could be helpful.
