Created attachment 84982 [details] dmesg Blu-ray that playback without any issues on UVD in mplayer2, stutter in XBMC (in both cases VDPAU is enabled and used for video decoding). BDRemux sample: http://www.multiupload.nl/WVDLZSI9B0 "Adjust Refreshrate to match video" option doesn't make noticeable difference in this case. XBMC running not under compositing manager but in separate LightDM session. According to XBMC developers, they just implement VDPAU spec and if there is some issues with video playback, I have to report it to driver developers first.

Probably should be solved by this: http://cgit.freedesktop.org/~deathsimple/mesa/commit/?id=9334f7d0f16738b4817e853d6d8cb1432953abfb
Doesn't stutter anymore with current Mesa git and XBMC git.
