The copy protection stuff is HDCP, and I thought that most
implementations would work with connecting a non-encrypted signal in.=20
(so the fact that your PC doesn't encrypt shouldn't bother you TV, but
if you tried to take a VCR output into a non-encrypted display it
shouldn't work). The protocol is stupid simple though, so I wouldn't be
surprised if there was a card out there that supported it. I'd look at
something from ATI for this because they make lots of consumer
electronics chips also.

As far as the conversion from RGB to YPrPb, it isn't a big deal - but it
seems like everyone wants to charge like it is. I think that if you go
to Ultimate Electronics they'll sell you one for ~$100 or so. If you
get that you should be able to do full 1080i (or 1080p if your TV
supports it). You might have to write some mode lines for X - I don't
know if those are built in yet (they're not that hard to write).

Sorry I can't give more pratical details, I haven't done any of this
with a PC or anything like that. If you have questions about the
protocols or formats I can babble some more - but I don't know any
specific cards that can help.
