I'm really sorry to hear that you've been experiencing this issue, and apprecieate that you've been having some other issues lately, as you described in your other post.
I've run some testing on your TiVo® and can see some issues which will need addressing. The signal strengths are too low and your Hard drive is also reporting an issue.
I'd like to arrange for a technician to call out and investigate further, so will send you a private message in order to get things arranged. Please look to the top left of this page where you'll see a red envelope icon, click on this and you'll see my message.
