hd receiver box all together? Tis the season for all gadgets to try and play nice together but I can't figure this one out. I have a sony blu ray player (bdp-s350) a directv receiver that has 1 component, 1 optical and 1 hdmi slot, a new xbox 360 4gb with 3 usb, 1hdmi, and 1 optical slot, a Samsung LN52A750 TV, all trying to go through a Yamaha htr-5840 receiver. Currently I have the blu ray, directv, tv, and receiver all working together but with the addition of the xbox, how can I make them all get along without having to play xbox through the tv speakers? I have attached links to show the inputs to all the systems above to make it as easy as possible to see what I'm talking about. Any help is appreciated!!!!
