Hi nicola71313,
Thanks for getting back to me!
I'm glad that's working for you.
I've run a diagnostic on your TiVo® and there is an issue with the signal coming into your box as well as a few errors.
It might be a good idea to send out a technician to resolve this as it's quite likely the issue you've had will reoccur.
I've sent you a private message (purple envelope at the top right of your screen) so I can arrange an appointment.
Look forward to hearing from you! 
Josh
