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:

"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.
