Welcome to the Virgin Community, I'm massively sorry to hear about the problems with your TiVo box at the moment.
The TiVo will make a little noise while working away, but not enough to distract your from watching the TV! So far that reason I'd like to take a closer look at this from our end for you. To allow me to do that, could you respond to the private message I've sent with the requested information.
You can view the message by clicking the purple envelope on the top right of this page. I look forward to hearing from you
