[mythtv] Inverted colors on viaXvMC (Epia)

[Martin van Es]

And for those busy with this issue: Now that it's all fine and dandy
on my 'main' mythtv system, one of the frontends (my i810 based
laptop) is normal on hue, but out of tune on brightness. Even bringing
that back from 50% to 0 looks (a bit) washed out still...

xvinfo while wathing liveTV, brightness set to 0%, contrast to 50%.
Color and Hue aren't adjustable (the value skips to -1 while trying to
adjust and stays there).
