Seems that during a storm my 622 doesn't allow me to watch an unlimited amount of OTA. We've had a couple of lengthy storms the last few days. When I get the lost signal screen I can usually go to the menu, guide, and pick an OTA channel to watch. But after a period of time the guide goes away and it seems that I can no longer watch OTA. Anyone know why this happens? Is the 622 "pinging" the network and if there is no return the guide disappears? I'm guessing that I can watch about 20 min or so of OTA before it goes away. I have my OTA input split so that I can always switch to watch through my TV but then I don't get dvr capability of course.
