Re: mplayer-vdpau and 195.22
Your GPU only supports VDPAU feature set A (see the README for more information). Feature set A does not support DivX/XViD decode acceleration, i.e. ffodivxvdpau doesn't work. OTOH these codecs have modest requirements, so usually acceleration isn't needed even on slow CPUs. Try something with H.264 or VC-1 instead.
