Since I got my new tv 3 months ago I have tried many things to make
mplayer work well even in 24hz screen refresh. I have, among other
things, tried modifying speed by calling build_afilter_chain with
modified playback_speed. But that changes the timing to much so that a
few frames will be displayed to quickly.

No, after 3 months, I have code that works very well. I have other
things I need to get working apart from mplayer and want to do other
things than trying to find out how the audio parts work. If you can give
me the code to call from mplayer.c to change audio so that the timing
for next frame only changes a few ms, I can try it, otherwise I would
now like to spend some time viewing movies using mplayer on my tv.

I have now fixed so all flickering I had with vdpau when window is
resized, is gone. The only thing I could add still, to vdpau, is
handling of blitting now when it also is synced to vsync. It now works
nearly like overlay, only slightly more inexact display time.
