OK, more interesting info. I recompiled mplayer in debug mode and found
two things:
1) It doesn't hang. It just becomes really slowwwww.. Like 30 seconds
   per frame or so.
2) It spends all of that time switching between functions with
   meaningless names in fgrx_dri

How come? My system can do over 10k glxgears! Is that scaling shader
THAT slow?
OK, joking. Can something be done to find out what exactly is causing a
problem? Even software-emulated -vo gl is MUCH faster than that.
