is there any signal loss or drop in quality if you run a component source through an av receiver before it gets to the television? i've got 3 component source components (dvd, xbox, gamecube) and 2 component inputs on my television. thinking of running the av receiver and the dvd player direct to the television. then running the xbox and gamecube into the av receiver. will there be any drop in quality on the xbox and gamecube as a result of this?
