I am on WinXP SP3 and i Experience the same problem :
When i am watching a 24fps movie with refresh rate @ 60hz, it's super smooth during something like 10-15s, then it's jerky for 2-5s. The jerk seems really regular. I have no problem when i watch the same movie at 24Hz.

I don't know if it can help, but when the jerk occurs, it has at least 3 periods :
t0 = supersmooth
t9 = jerk
t9,5 = supersmooth
t10 = jerk
t12 = supersmooth
t12,5 = jerk
t13 = supersmooth
t18 = jerk
...
The timing are approximative I might retest to give more accurate timings, but the jerk starts every 9s that's sure.

I have tried a lot of settings, with 2 different GPU (ATI HD3200 and Geforce 7600GT) without any improvement.

I don't know if the bug comes from xbmc or from the os or the drivers, but i can see the same problem with windows media player and MPC-HC. Note, they all use ffmpeg, perhaps I should give a try to CoreAVC ...

I confirm that I can't see any pb in the Codec Info bar (no frame drop, nothing special with aq/vq nor fps)

Regarding VSync, XBMC is set up to "Let Driver Decide" and driver is set to enabled.
