"Are you saying that if my components (DVD player) can output RGB OR Y,Pr, Pb, and my input source (projector)can accept either type of signal, I should use RGB because it isn't compressed???"

Another wrench in this equation is that almost all DVDs have copy guard protection built in which the DVD player will read and not send out an RGB signal. I always run a component cable along with an RGB so that you can watch all of your DVDs.
