(Get the code!)
I am running 12.04 with nVidia-vdpau installed. In nVidia Settings, Sync to VBlank is enabled by default for BOTH xVideo and OpenGL. There is no such setting (that I can see) affecting vdpau.
When login in with session type Ubuntu-2d, CPU keeps near 0% usage when playing H.264 video at 1080p with uMPlayer configured with vdpau.
Problem happens ONLY when Compiz is running; same H.264 1080p video shows 40-60% CPU usage on all 4 CPU's.
