I'm thinking about moving to another place that'll require my PC to be downstairs, and my TV to be upstairs. I've already got a great RF remote that'll let me control it from upstairs. However, is there a way to extend the 1080p video from downstairs, to upstairs?

I have a Radeon X800. The 7-pin mini-DIN connector on the back will output to a Y/Pb/Pr component cable set, provided you have a compnent adapter.[1] [2]
There are YPbPr-over-twistedpair extenders that can send signals for quite some distance... so the shorter distance I'm interested in, it should result in very little loss.

COTS S/PDIF extenders:

Y-Pb-Pr takes up 3 of the 4 cat5e pairs. S/PDIF can either be run on the 4th pair, or be run on a second cat-5e cable.

Practicalities

For wiring up the extenders... There should be extra wall sockets at each end, to send the cat5 from downstairs to upstairs. The cat5e can either be wired directly, or it can run through the central switchboard. The extenders will be outside the wallplates, so if/when I move, I can take the expensive parts with me.
To avoid having to switch video resolutions, I should pair this with a normal 1080p LCD downstairs. (wait: do any exist? Or are all 16:10?)
Also, is there a way to avoid having to switch my audio card from S/PDIF encoding to

DIY

But you can do the twisted-pair differential driver circuit yourself too.

Numerous webpages seem to say that 1080p over component cables = 148.5 MHz
For transmitting S/PDIF, most webpages seem to say that it's sent at under 192 kHz, so that should be a piece of cake compared to 1080p YPbPr.
video circuits: one (200mhz), two (250mhz)
