This thread was over a year ago.  Any progress on this issue?  Does 0.22 
allow adjustment of brightness/contrast on playback?  Will we ever see 
that functionality again (I'm running 0.21 and see no sign of it 
working)?  Will I ever get the efficiency of my old AGP FX5200 that used 
less CPU on my 3200+ Athlon than my 7600GS does on my 4200+ dual core 
system?   Am I missing something by not compiling from source (instead 
of using Axel's excellent packages)?  Is Nvidia still insisting on not 
providing the xv overlay?  Do I need to alter my xorg.conf settings to 
get the new functionality?  Does anyone know of newer/different cards 
that provide the overlay (newer Nvidia, ATI, Matrox?) or that support 
some new standard?  If the Myth devs support the OpenGL-based approach 
that Mr. Dean mentions, can we expect similar actions from the devs of 
Mplayer, Xine, VLC, etc, etc, and will it lighten the load on the CPU 
the way the xv overlay did?

Sorry for the rambling list of questions.  Just trying to get up to 
date.  Thanks.
