Stanley, do you have "Enable picture controls" checked in the setup?
It's in Setup->TV Settings->Playback on the first screen,
"General Playback (1/9)".

If so, VideoOutputXv::InitPictureAttributes() should be checking if
each picture attribute is supported and setting supported_attributes
with a mask containing the supported attributes. Then this is used to
determine which attributes are visible in the OSD.

I've only verified that this works for OpenGL video output. If it isn't
working for XVideo it's probably a bug in InitPictureAttributes().
