Advertisements I haven't been getting the grey screen too much, but my Tivo keeps freezing on certain channels. Then I will switch to the other tuner, and it will be on a different channel and work fine. So I will switch back and it will still be frozen, so I will change the channel and they will work fine. For example, E didn't work for me today for about an hour. I keep doing a hard reset just about every day. Any idea why this keeps happening now? It hadn't frozen since I first got it months ago.
