I would try the direct connection without the dithering or 16-235 xbox setting to see if you still have the dark issue, and if not maybe the level issue will be gone also.

I would try the direct connection without the dithering or 16-235 xbox setting
to see if you still have the dark issue, and if not maybe the level issue will
be gone also.

I would also try with another player like mplayer.

Do you have issues with this mpeg2 full range ramp?

I would try with current set up and normal settings/different player etc.

Of course normally (= player stretching 16-235 to full) the end 2 blocks will
be the same, if xbmc is managing to use full range then they won't be.

What you see will also depend to some extent on the levels
(brightness/contrast) set on the TV.
