Having just purchased a projector (benq pe5120) I am now thinking of buying the denon avr1705. The problem is I am very confused on how I can easily switch between video sources. The kit I have is Philips 32" TV, Benq PJ, Sky, Xbox and Sony all in one HT. The PJ will be connected via component as will the xbox. Everything else will probably be s-video. Will I be able to switch video sources, ie watch sky on PJ or xbox on TV? Will it convert the s-video signal and output to PJ via the component out? I may be being rather dumb but any advice would be appreciated.
