I thought that 0.90 already had the sub-picture updates but apparently
not. CVS version has the required changes.

Without the sub-picture layer the OSD stuff will be mixed directly to the
CRTC2 surface. This means that mplayer will need to read from video memory
to do the blending. Reading from video memory is quite slow.
With the sub-picture layer the hardware performs the blending so that
reading from video memory is not needed.
Fortunately the OSD stuff is usually quite small so the reading shouldn't
have much impact on performance. I haven't really benchmarked this.
Also you save some video memory by not using the sub-picture layer. Around
300 kB - 1.2 MB depending on TV standard and buffer mode.

You can adjust brightness,contrast etc. with keys 1 - 8.
