Have you ever heard of a "Balun"
I gather it's a passive adapter for video/audio sources to convert to Cat 5. That's normal internet style wires that has an end like a telephone cord. Check this out.
CableTV to RJ45 Balun: Run Cat5 (easy) where you would normally have to run cable lines (annoying). Works like regular cable lines for analog channels up to 77. I'm pretty certain that the digital channels run in between the lower channels, so this would work with a receiver. Hmm
SVideo and Audio over Cat5: Here's where it gets interesting. With all the talk of Personal Video Recorders and Home Theatre Computers, this may be the solution. Hide the computer in a closet on the other side of the room, and run the signals over a single wire. Control the PC with a Gyration "in-air" mouse.
Shit, there is so much I don't know about everything.
