Just got one, and on day 3 or so, it stopped responding to remote commands. I seee the box orange light blinks on when I press a key on the remote, but there is no visible response from the box. This has happened several times now, about once or twice per day. When I cold reboot the box, when it comes back I can't view live tv for a while, as it has the "acquiring channels" screen with the swirly icon. When I first got it, I had some trouble activating my cable card. I'm wondering if it's related.
At this point I'm considering if I should replace the TiVo, the cable card, or both. Anyone have a related experience or comments?
