You don't need to modulate the video. Use Coax. For component,
use 3 coaxes of EXACTLY the same length.
You don't WANT to modulate the video if you don't have to.
Google for IR stuff, there are plenty of things that let computers
"See" IR and IR receivers can be run pretty far, wiring wise. CAT
5 is probably overkill, thus safe.
As far as receivers, there are many many receiver chips cheap at
electronics houses (jdr, jameco, digikey, etc, etc). I've seen (and
ignore) projects that can use the IRDa porton the computer to send
to it. Google.
