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.
