CPU load is 1.1% while mplayer is running, so the system is not busy...

Well, I read somewhere 8600GT has some better level of VDPAU than the
lowest one. I don't remember which level it is exactly - there is a
good wiki page on that.
Anyway, the same file is played perfectly well and with a
minimal CPU usage (somewhere between 1-5%) when mplayer is started
from a terminal window. It makes me think that VDPAU really works on
my system and it's not a problem of some particular video file...
