Hi there Pj6,
Really sorry to hear about the issue experienced concerning your TiVo® service.
I've looked into this for you and it seems this is due to a high demand for our service in your area.
There is a fault ticket raised for this under the reference of F004669287, with a review set for 16/11/16.
I am sincerely sorry for any inconvenience that this may cause.
Please let me know if there is anything more that I can do to help.
Who's who? Find out more about our community members. Good folk to know
I have responded to your separate thread to advise that the fault ticket reference mentioned now has a review set for 29/03/2017.
This, however, no longer appears to be related to the cable that you're currently connected to.
Having had a look at the equipment levels, there does appear to be an issue present, which I believe would now require an engineer visit to resolve.
I've sent you a private message so that we can get this arranged.
