Great work neuron2! Its people like you who motivate me to do great work.

My setup consists of a q6600 cpu, 8500gt, and 2gb of memory. Tests where run on a raid array.
I'm using Vista 32bits and such got rid of nvapi.dll and nvcuda.dll

compared vs ffdshow filter (my usual method).

Video is 1080p from a bluray with no post processing .
