My downstairs main Tivo box has been having trouble for a number of weeks. I have rung up about it a couple of times but they tell me to switch it off then on, say they'll check it and say it's ok, so I thank them, but nothing has changed. My recordings stop and start then break up into pixels and the recording is impossible to watch. The Menu and small TV picture take a while to come up when I press Home, then all goes quiet and dark, eventually the menu appears. Compared to my upstairs Tivo box this box has now gone so slow, with recordings not worth the effort of recording and I regularly clear my recordings off. That doesn't make any difference though. Not sure what I should do next about this. I have five VM TV boxes in my house, two are Tivo and three are HD. The other four boxes are ok.
