I have forwarded on your details, and this is what I have received back.

Hi Peter,

We’ve looked into the case history and the customer has reported poor reception.

The customer’s current address comes up with “likely with high aerial”, and the customer has advised that he just has a regular aerial, not up high.

The customer has also advised that he is moving to a different address where the Freeview|HD coverage shows as “very likely”, and advised that he would report back to us once he has relocated.

I hope this is of help but please feel free to let me know if there is any misunderstanding
So as far as they are concerned they appear to be waiting for you to move house and see if the problem remains.

It is true that a twin tuner TiVo requires a better signal than a single tuner TV or STB. so if your signal quality (not strength) is marginal it may not always work with your current setup. it could be a simple as a bird has done a little damage to your aerial which was enough to push a marginal signal to no signal (on TiVo). With digital once you reach that point signal disappears, there is no in between.

Peter.
