Just purchased a brand new tivo roamio pro. I'm upgrading from my premier Xl. I have an m-card from my previous tivo(nds). After calling up to have my m-card binded, and completing set up I kept getting zero stations, ever channel was coming in as a black error v52. I worked with cablevision for about an hour over the phone. Tech suggested I go exchange m-card. I Exchanged the card called cablevision again rebinded. Same problem. Called tivo support. After many reboots and attempts to get it to work they called cablevision. They attempted many things. Still black on all channels. After an hour tivo said it was due to a low signal. (Maybe to many splitters) I tried moving the tivo near where the cable comes into the house. Still nothing. Any suggestions this is killing me.
