What's going on with the "What's on" menu function? It's one of my favorite features on my Logitech Revue and worked fine until about Christmas day. Now it's mostly unresponsive, working fine one day, then dead the next day. System resets (both soft-Ctrl-Alt-Del and full restore factory settings) fail to improve the situation. I've seen a couple of posts from others who have reported this problem. I wonder how widespread it is. Is GTV consulting a service from my cable provider or does Google have all this information directly? Any way to "wake up" the What's on service?
