I have now built on your patch by adding knowledge on the vsync interval
and vsync time so that it can better align display and dropping to get
best showing of frames. I can also identify when the blitting engine is
used so that it can be handled differently from the other one. Though
VDPAU is missing a good way to easily get the vsync interval.

Now I can watch a move on a screen where screen refresh rate is nearly
the same as the movie fps.

I could add options so that vsync alignment can be turned
on/off/modified and an option to set number of output surfaces to use.

As my patches for vsync handling has not been in the way you prefer, I
wander if I should continue or if somebody else will fix it?

If you want me to continue, what options do you want to have?
