I'm having an issue with a few videos in the collection
This one is the most serious as it's one of my favorite films and it will not play correctly if I enable refresh rate changes

There are 3 attempts to play the movie.
The first is from time 0 in the movie (Timestamp 21:44:31). The movie starts at the correct frame rate but as my UK TV doesn't support 29.xFPS the refresh is 60
After about 30 seconds refresh switches to 23.98 and playback goes to hell as you'd expect. This happens consistently
Then I stop and play again (Timestamp 21:46:07). This time from a resume point at 18:3something. Playback starts at 60FPS then switches again to 23.97 with heelarious stop motion effects. This runs for a minute or so when I stop it. I then resume playback (Timestamp 21:47:35) from the last stopped position, 19:30 odd and despite the pullup correction warnings it doesn't switch refresh rate before I stop (although it might if allowed to continue)
One thing I notice is that before the refresh rate change the rendered FPS in codec info display is all place from 40something to 60 odd
After the refresh switch the rendered frame rate is solid at 23.96

The log is from openelec build OpenELEC-Generic.i386-devel-20120125153526-r9647
This indicates XBMC 11.0-BETA2 Git: f76c547
OpenGL version 4.2.11318
settings
Direct XVBA acceleration with shared surfaces enabled in the logfile.
The same behaviour is apparent with vaapi enabled or with all acceleration disabled
Logfile was with Advanced shader as render method but behaviour is the same using software rendering too
Sync playback to display is on with Video clock (drop/dupe audio) sync method
I have also observed the same CPullupCorrection eerrors happening on Windows Eden Beta 1 (and all versions prior to that)
I do also have a few other video files that exhibit the same CPullup errors but none of them seem to make the same bad rate switch, they just keep exhibiting some stutter while PC drops back to None then carry on again when it's re-established
