 	... but it could be if one could phony up a fake Xv mode.  No 
reason why RGB can't be used as generic D/A outputs and spew raw YPbPr 
data from the MPEG stream to them.  Any card with sync-on-green could 
potentially do it.  Technically, bipolar sync would be required for 
anything above 480i/p, but I bet that most HDTVs would work with the 
unipolar sync.

 	Something I've been meaning to try but havn't had the time (and I 
can't code for crap).
