I have a CL PC-DVD Encore 5X drive and want to connect it to my TV. The problem is that my TV is very far away from my computer. Can you buy a 50ft or so S-VID cable anywhere? (I think it's an S-VID cable.) Would I need to go to a custom cable place to get one? If so, where can I find one of those? If not, are there some sort of length rules for this type of cable like in Ethernet? A Radio Shack guy once said that RCA cables had a 15ft limit. I think he's full of it. Can anyone help me?

Thanks!
