Intermittent signal loss with newly installed Tivo box .
Have not had a Tivo box long and now it is developing signal loss sometimes when I change channel or when I turn the telly on . The Tivo box is always turned on and sometimes one of the green lights on the left hand side starts flashing and that is when I think a signal loss occurs . All the cables are connected but it can be a pain when this occurs . The said box is a Cisco model . I am due an engineer tomorrow who is supposed to install another Tivo box in my sons room but I am beginning to think that if this is a continuous fault I would probably be better off going back to my original VHD box which seemed to work most days .
