I'm pretty new to the world of HD televisions so please be gentle with me. I have a pioneer elite pro 710hd television and I have my DVD player hooked up to it with a 10 foot component cable ( v2 Tributaries maximum performance ofc video cable - model DCVC ). I'm moving my equipment rack further away from my TV and I need to get a longer component cable. The new length I need is now 20 feet. I intend to trade in my cable and buy the exact same brand and model of cable. I have heard that longer runs of cable will give you poorer performance. Will I need to worry about getting a poorer picture with a 20 foot cable instead of a 10 foot one? The cable is a fairly expensive one. The 10 foot one was $220 ( Canadian ) and the 20 foot one is $310 ( Canadian ). Any information is greatly appreciated.
