What kind of cable to use to route video from comp to TV?

I know it's not a repair question, but I figured this would be the
best place to ask.
I'm setting up my computer to use as an HTPC. I have a GeForce 2
MX200 with s-video out & composite out. The picture's great with the
s-video to the rptv 20 ft. away, but I'm trying to send the composite
signal to the 36"er on the next floor, about 50 ft. from the comp. I
tried cat-5 wire because I've read about it being used to wire up
houses. The picture is all wavy, discoloured, etc.
Can anyone recommend what wire to use before I go spending more money?

Thanks,

Chris

I should say that I'm not too worried about the video quality, as I
only plan on using the upstairs TV to see the jukebox program while
I'm listening to music.

Any 75 ohm FULLY shielded cable should do, but you might wind up with a
ground loop causing a moving bar up the screen simply due to the distance.

CAT 5 is only a twisted pair and not rated for the type of analog signal you
are trying to send.
Correction: CAT 5 is not suitable for unbalanced circuits (like the
video & audio output on your PC) so....

either: get some cheap TV coaxial cable (the easy&foolproof way)

or: (EE degree recommended...)
- Buy the appropriate conversion chipset (for example MAX4444/MAX4447
for video and DRV135/INA135 for audio)
- Design transmitter and receiver circuit
- Build prototype
- Test prototype
- Evaluate results
- Apply fixes (if necesary)
- Document fixes (you'll probably end up building more of them for
friends and relatives, some day)
- Rig up the gear, sit back and enjoy the fruits of your labor ;-)

Thanks. I think I'll stick with the coaxial cable :)

RG6 Quad shield will do fine.
99% or better RG59, RG59 mini, or similar will also work.

Hi,

These gadgets help get around that problem
