Fixed in 185.18.14 NVIDIA Driver.
Maybe this is it.

I can play the MGS4 trailer smoothly with/without Cool'n'Quiet now.
With VDPAU: 7% CPU usage for 1 core in Phenom2 x3 720BE@3.2GHz.
Without VDPAU: 60% CPU usage for 1 core in Phenom2 x3 720BE@3.2GHz.
Also it will improve VDPAU with PowerMizer performances.
I can get the stable results of qvdpau now.

I couldn't feel it, but "-framedrop" skips movie frames.
I don't recommend it. :-)
