I just got a Revue, and when I am trying to set it up I am running into issues. First, my Directv box has no HDMI port, so I thought I was just supposed to hook it up to the TV, but that doesn't seem to be working as nothing comes up on my screen when I turn on the Revue. I don't get the setup menu, or any indication that the Revue is doing anything. It just stays on Directv channel I was watching. Am I able to use it without having the Directv hooked to HDMI? Is there another cord I am supposed to have to convert, or am I just missing a step somewhere. Thanks!
