Good find, I did not see this one. Reads very much like my case. With vdpau the video goes
at about twice the speed, and the A/V Sync rises to over 600 before dropping very low,
when the video gets to "normal" speed for a fraction of a second and then returns to very
high speed.
Without vdpau the video is stable at the wrong speed, e.g. Video=50Hz, FPS=60Hz. Again, when
A/V Sync gets to over 600 it drops away, FPS goes to 50Hz then immediately rises to 60Hz.
So it is not always twice the speed. A 50Hz Video runs at 60Hz, but using vdpau it runs at 110Hz
(very variable, between 100 and 120Hz).
One thing to add: mythfrontend often hangs on exit and "needs killing".
I also see very many of these messages logged:

I get the impression that the video, at times, plays as fast as it can get data rather than
keep to a desired FPS.
