4 tuners only able to get 3 one with no signal. I got tired of Tivo saying is a Fios card problem even after i replaced a Roamio once and two diferent cable cards with the latest firmware. Just tired after 3 weeks of back and forth and closed account. Its a Tivo problem but they will just not admit it. I was only getting 3 tuners and one tuner without a signal then I programed Roamio to only receive 3 tuners and now I get 2 good tuners and the third with no signal making my season pass a crap shoot. Some will record and others wont due to no signal. Lost money on Roamio will try to sell. Its a shame because i liked tivo.
