[mythtv-users] VDPAU Brightness or Gamma Settings

I upgraded my living room FE box with a GT220 card. Works great. VDPAU is
solid. I can now play some 1080p content that the old card found problematic.

However VDPAU evidently does not use the xorg.conf gamma setting. In fact, I
found one posting that seemed to say that VDPAU doesn't offer gamma controls
of any kind.

How does one adjust gamma or at least brightness & contrast when running
VDPAU? I am aware of the per-channel brightness settings in MythTV. That's not
going to work here. I need something unique to this FE & display combination
and global to all playback on this FE.

I made sure the screen controls option is enabled in setup. However I don't
see any controls options in the OSD menu during playback.

I have the proprietary Nvidia 190.53 driver installed.

Any thoughts would be welcome.
