Re: mplayer vdpau
Looks like the frame display times reported by VDPAU are a lot less precise if the video overlay feature is disabled (because of X composite extension being enabled or another window already using the overlay). The code estimating video FPS can become unstable in this case. So for now the framedrop/timing code only works reliably if you're using overlay. I'll add a workaround for that later (at least allow specifying display FPS manually to use the code if nothing else).
