[mythtv-users] Display YUV on RGB *without* remapping

Hey all... I've got yet another hair-brained scheme to get good
tvout on the cheap. I know that Xv is generally used to play video since
MPEG data is YUV but the output is RGB. Has anyone ever seen a driver
setting/hack to send YUV data *directly* out the RGB? Many cards can do
sync-on-green, so with the Y data on the G channel and the other two on
the R&B, one could get component video *directly* from a VGA card.
Something like:

is all that would be necessary.
It'd be great if the 2D X driver would do such a thing as well,
but video should be somewhat simpler since no transformation is necessary.
Does Xv provide anything else besides color transformation and hardware
scaling?
Food for thought...
