I think it also works with Geforce9300/Nouveau > but need to double check again. Apologies - I should have clarified I was talking about nouveau specifically. The issue is multi-threaded submission, which mpv (at least at one point) attempted to do with hwdec + video output in separate threads. mpv -vo vdpau --hwdec vdpau should work. But it doesn't, at least not in my testing. Hits an assert in libdrm about rather incorrect usage. Haven't investigated it though. Like I said, this works fine with mplayer. This is my preferred player, so I tend not to go much further.
