No it means you didn't make the correct sacrifice at the dark of the
moon. A rooster is good but a goat is better.
Seriously, try 'mplayer -vo xvmc -vc ffmpeg12mc ....'
That's the really secret incantation. xvmc will not work without both of
those switches. But you can always use mplayer -vo help and mplayer -vc
help to see all the secret incantations.
All the rest of the stuff you listed looks right. Check the wiki to make
sure you have all the correct things in your xorg.conf.
