I recently picked up a Revue. Love it. However, I don't have cable and use an old school Sony SAT-HD300 DirectTV box to get OTA HD. It has a DVI output which I convert to HDMI to my TV. I was hoping to connect the STB to the Revue so I can use it on Sundays for some NFL action. However, I cannot get anything to appear on the screen when I am trying to set it up with the Revue. But the STB works fine when connected directly to the TV. Any ideas why this is not working???
