Welcome to the Virgin Media Community, I'm massively sorry to learn about the problems you're experiencing with your TV service at the moment.
I've been able to locate your account and run some tests on this for you. We're seeing some problems with the TiVo box and I'd like to arrange for an engineer to come and take a closer look if you're available?
I've sent you information regarding this in a private message, you can view the message by clicking the red envelope on the top left of this page. Sorry again for the inconvenience this has caused, we're looking forward to putting it right!
