    The is no UVD support on RV770 at this time.

    [VD_FFMPEG] Trying pixfmt=0.
    Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
    VO: [vdpau] 1280x720 => 1280x720 H.264 VDPAU acceleration 
    [VD_FFMPEG] XVMC-accelerated MPEG-2.
    A:  18.1 V:  18.1 A-V:  0.000 ct: -0.001   0/  0  3%  1%  1.4% 3 0
    I find this a bit confusing: H264/MPEG2, VDPAU/XVMC - which is it then?
    I think it's using VDPAU... But I'm not sure, don't know too much about mplayer's outputs, that is confusing...

    Clip info:
     major_brand: mp42

    [stream] Video (+) --vid=1 (*) (h264)
    [stream] Audio (+) --aid=1 --alang=und (*) (aac)
    Trying to use hardware decoding.
    Selected video codec: H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [lavc:h264]
    Selected audio codec: AAC (Advanced Audio Coding) [lavc:aac]
    AO: [pulse] 48000Hz stereo 2ch floatle
    VO: [vdpau] 1280x720 => 1280x720 vdpau 
    [vo/vdpau] Compositing window manager detected. Assuming timing info is inaccurate.

    Anyway, thanks for all the help. With this and hardware accelerated flash working at last I couldn't be happier.

    Thanks again for everything!
    Yes, mpv's outputs are nice and clean, and to use hardware video decoding with vdpau on mpv all you need is --vo=vdpau and --hwdec=vdpau
