How do I get my home theater to display through my HDMI projector?

on many Receiver you have to run the audio separately from the HDMI for the equipment to the Receiver the HDMI only switches the video so use an optical or a digital audio out put from the PS3 an X box and the cable box to the Receiver and switch the video only to the projector that should work for your set up. The non HDMI will only show up if you have a unit that up converts other wise you need to run the video separately. You reciever may have multible video outs one hdmi and one componet and one composit check that out if so it will switch those too.
