I had everything set-up. The TV mode was working, I got my local Cable channel guide for Brighthouse Networks, My DVR list was working as was my browser and yahoo home page. Since then, when I watch TV through GTV, after about 40 mins. the screen goes black. I have to unplug the Logitech Revue and plug it back in, just to get back to the Google Home Page, but the TV bookmark is greyed out and I can't get back to TV Mode. No wonder they lowered the price to $99. Any suggestions?
