Created attachment 68485 [details] vdpau output
You said was now ready vdpau but when I try to watch a movie with this output on my radeon 4650 , the video run with some lag :(
R600 vdpau decode isn't perfect, depending on content you may notice some inaccuracy.
With x86, it probably won't beat CPU decode unless you have something old/slow and single core.
The lag you see I can recreate - it seems to be a mplayer2 issue, "real" mplayer works OK for me.
