OK - I'm going to test the shorter HDMI this weekend
AS far as sources go, I have a Marantz DVD that has upscalling, but I've used it very little with upscalling. I kept it using component video. I'm going to need a switch at this end to choose from PS3 and Marantz so that I don't need another very long hdmi. By the way, since I'm going to need a switch on this end, should I keep the booster/repeater on the projector end?
But I can easily get another PS3 from a couple of friends. Testing with a different PS3 should work also, shouldn't it?
