Welcome to the Community, I'm really sorry to learn about the problems you're experiencing with your TiVo box lately.
I've been able to locate your account and run some tests on the box from our end for you, we're detecting some signal errors and I'd like to arrange for a member of the team to come and take a closer look, if you're available?
I've sent you information regarding this in a private message, which you can view by clicking the purple envelope on the top right of this page.
Sorry for the problems you're experiencing with your TV service, if you'd like a member of the team to take a closer look at your individual account / service, I'd need to request you to create your own thread, that way we can be sure we're getting back to you.
I'm sorry again for the inconvenience this is causing,
