I have a 3416 comcast dvr motorola box. I have a samsung hdtv. It was working ok, with hdmi hookup, but now I have nothing but a message on tv that says something like "this channel should be available shortly" It has said that for a whole day now. I called Comcast and they sent out a signal, and said the box was fine. I can record and watch the dvr recordings, but cannot watch tv per se. Please please help I need tv!! ( I tried unplugging box and waiting too)
