I think I figured out how to do it without that box actually. I'm glad I kept looking at it before I left. There is a monitor out on the receiver that goes to the video in, which allows the TV to just be a display. I should then be able to hook up everything else to receiver. I'm still trying to get it all put back together, so we'll see. I started thinking about that other box, and didn't see why it would be able to do something that my receiver couldn't already, with all the jacks it has. I think I'm going to be ok and just needed to think about it all a little more.
