Now some new source/videos, is comming with VFR (Variable Frame Rate). Is there any kinde of support for that video container, in the XBMC for RaspberryPi ?
Especialyy video dumps from Silverlight, that use DASH streaming, with VFR. Offen variable from 23-25fps.
I know, that even a VLC player, on a PC, can't play them, without movie "jitter", where fps is going up or down.

Don't really understand the question. If the video is variable framerate (which has always been supported in mkv, mp4 etc) then we'll play the frames at the timestamps requested.
Obviously syncing display to framerate makes no sense, so smooth pans would not be possible (on any platform).
