Using full range video output from Ubuntu, monitor set to limited range RGB and playing video with mplayer2, everything seems to be in order. Levels are correct, BtB and WtW are there, no banding in greyscale ramp. No oddities in resolution tests either, although I haven't looked for chroma issues yet. I also checked static RGB images with same results.

My command line:
~/src/mplayer2-build/mplayer/mplayer --colormatrix-output-range=limited -vo gl -fs

I will next try the VA-API enabled mplayer (if I can make it build) to verify that hw decoding works properly. Maybe the issues are with XBMC YUV-RGB converter.
