mplayer -vo vdpau -vc ffh264vdpau movie.fileTrying to use SMPlayer as a GUI was not very successful.

Well it doesn't matter. I am fine with mplayer and so I added just some additional lines for more comfort into /etc/mplayer/mplayer.conf:
vo=vdpauFor working smoother with mplayer here my favorite keyboard shortcuts:
p / SPACE - Pause (pressing again unpauses)
q / ESC - Stop playing and quit
# - Cycle through the available audio tracks
f - Toggle fullscreen
