but as far as i know, even vdr has the 4-color limitation on it's menu.
it does use multiple windows with different color-spaces to display
more colors though. this should be possible with multiple spu-streams 
with different color-luts too.

i once had another idea:
get the iframes from the currently playing video stream and overlay
the osd data on these images (and display this as i-frames only).
i think this should result in a quite similar effect to the way
it is displayed now, without using too much cpu.

just my 2cent.
