Can I run composite cables off of a H23-600 receiver along with component cables? I have a TV in one room that rarely gets used but does when kids have friends over. What I want to do use component cables to my sons TV in his bedroom and then run composite cables to the TV in the other room. My HR23 is RF capable (and the remote) so I figured they could go into that room and still control his box yet watch TV in the spare room. Feasible?
