Ah, in that case tweaking your mplayer config might really help. Look at
the man page for options (-vo gl:...).

You really have to try every option and sometimes reasonable
combinations. I've found that even if the man page says it is a slow
option, sometimes it's the fastest. As I've said before, you will reach
the maximum number of texture units in your card, therefore certain
options will not work together but the man page tells you how many
texture units each option needs. With that info it should be easy to
tweak your settings.

To get you going, try mplayer -vo gl:yuv=2:lscale=1:cscale=1 <file>
Don't forget to test it in fullscreen mode.

You can later apply these options either in /etc/mplayer/mplayer.conf or
in ~/.mplayer/config like this: "vo=gl:yuv=2:lscale=1:cscale=1"

Hope this helps,
