Only mpeg 1 and 2 are supported.

Does VDPAU_DRIVER=r600 vdpauinfo find your libs - if not you may need to 
copy them to where ever vdpau is looking.

Compiz may complicate things - I haven't tested with it.

Depending on how it was configured mplayer needs (probably) 
/etc/X11/XvMCConfig containing /path/to/your/lib/libXvMCr600.so

Your mplayer is old - maybe svn would be better if you can build it.

mplayer -v will tell you more about where it's looking for things like 
xvmc libs - but with newmobcal you will also get swamped with transport 
stream info.

vanilla xf86-video-ati: 6.14.2 does not have xvmc support, but I see 
from your Xorg log that you must be using a patched/other version.

Generally r600 pipe-video still has rendering and functional issues. If 
you just want to test fair enough, but if you are trying to make your 
system play h264 that it can't currently the best thing you could do is 
compile svn mplayer which now has ffmpeg h264 multithread support so -

mplayer -lavdopts threads=4 will use all of your cores.
