The 8400GS card you have only has 256MB of RAM, which means you would
need to reduce the number of VDPAU buffers to get it to work.
In general, it will not always work depending upon the content you are
decoding with that much Video RAM, but in one FE I have that has such
a card, setting the vdpaubuffersize=12 will allow most content to be
played back using VDPAU, as long as I don't do any deinterlacing on
the content.

You set the vdpaubuffersize in the filter section of a playback profile.
