Howdy. You should run all your video inputs to your receiver. Then run one video out from the receiver to the projector. Giving your receiver can do that. For a projector get a 1080i resolution at least. Dont forget the screen makes a big differance also. Ask to demo a projector at a local HT shop. Ask what screen would be good for your application. Cable will cost some moey if long run. Might want a signal booster. Depending on what you can spend , get auto focus if you can swing it. Check reviews on projectors in your price range. Good luck.
