Welcome to the Community, I'm really sorry to learn about the problems with your TiVo box at the moment.
Although the TiVo makes some noise, we wouldn't expect it to interrupt your viewing or affect the service in any way, if that is the case then I'd really like to take a closer look at this for you.
To allow me to do so, respond to the private message I've sent with the requested information and I'll get right to it. You can view the message by clicking the purple envelope on the top right of this page.
Sorry again for the problems with your service, we'll speak soon!
