Right, i have s-video and RCA (composite video) out of my Radeon 7000 dual head graphics card, but my tv downstairs doesnt hav a SCART.

I need to run a lead 20 metres long to connect the PC and video.
Will RCA cable degrade the picture quality too much over 20m of cable? If so, would coax cable be a better idea (using an adapter obviously)??

20 M of cable would be fine. Coax would be slightly lower loss possibly, although the characteristic impedance may be slightly different. You won't need adapters, coax should terminate just fine in RCA connectors as long as you don't go for fat coax.

The frequency of the composite video isnt too high, so losses will not be overly bad. Some roll-off of the hugher frequencies may show as softened edges, but at the low resolution you are working with out of a video card, you won't notice it.

Thank you! I think i will go for a coax cable with an adapter then (as its the cheaper option!)

Any idea where i might get an s-video (male) to RF (female) lead or adaptor... i can't see any on the net...

Well, I am in New Zealand, so any local shops here might be a bit far away?

Just a tad! I've looked online, but can't seem to find anywhere...
