Im looking at getting a projector since my tv went out and want to run my directv,xbox,and dvd player to projector and my samsung theatre system for sound. My home theatre system in a box only has one hdmi output. So can I run a hdmi switch box to make everything work or would it be easier,better to just go get a stand alone reciever and use the speakers from my current surround system? The projector has 2 hdmi inputs.
