Are you sure it is using accelerated decoding? CPU load should be just 
1-2%. AFAIR you still have to explicitly enable the hardware accelerated 
codecs with mplayer. It might have changed at some point. Also try mpv 
instead, maybe. It's easier to enable decoding with that player, just 
specify --hwdec=vdpau on the command line and it'll use accelerated 
decoding whenever it can.
