I has similar problem with jerky video on vdpau. After some
investigation I hope that I found solution. I was try increase volume of
#define NOUTPUTSURFACE 2
I am trying value 6 and it is perfect on nVidia G100 or G130 graphic,
and almost perfect on 8300/shared
I can confirm it on 3 machines, and I have confirmation from 2 other people.
