Re: mplayer vdpau
A quick note of assistance that those of us running MythTV's VDPAU implementation have noticed-- 256 MB appears not to be enough to run VDPAU at this time. If you have a 256 MB card, it may not be enough. If you have integrated graphics (as I do) try going into your BIOS and increasing the shared memory to 512 MB. This made the difference between VDPAU failing every time and VDPAU working perfectly for me.
