I never experimented with substitutes for the S-Video cable. I bought one 18 ft and one 60 ft cable from an electro shop, both reasonable good quality (gold-plated connectors etc.) and compared them to a low-end cable. The difference was clearly visible in that the image with the low-end cable is more fussy and less colorfull. This is probably due to the impedance of the cables. Moreover, co-axial cables have 75 Ohms impedance (if I remember correctly) to temper reflections of the signal so that would render them useless over a longer distance.

For my own curiosity, what composes an S-Video cable? I understand there are two signal conductors (luminosity and colour) each with their own ground in a shielded cable. Is each analog signal twisted around its ground? If so, could twisted shielded CAT5 work as a substitute? For long runs, would putting each signal on its own co-axial cable and running two co-axial cables be a better plan?
I have found it rather hard to find any S-Video cables longer than 12 feet. I eventually found a 25 foot cable. I am uncertain of the quality, but it was literally the only one I found in the city (though I probably don't know the best place to look).
Cheers, Shaun

Also remember to buy a *good* quality S-Video cable, it really matters! Keep the cable length as short as possible.
