My question is... I will have a denon dvd player feeding a projector via hdmi and want to also modulate the dvd thoughout the rest of the house. I know how to use a madulator and a combiner and a notch filter and so on. But my question is with my denon dvd player. Are all the audio/video outs always active. In other words if its going out to the projector on the hdmi will it also go to the modulator at the same time.
