Advertisements a week after a smooth NDS cc install in my tivo HD, i was not getting any channels on one tuner. after a call to cablevision, they reinitialized the cards, and the two cards are working fine. i basically had to walk thru the same install the original tech did except CV didnt need any version or id numbers off the screen. CV DID NOT KNOW CARD 2 HAD TO BE REMOVED TO RUN DIAGNOSTICS ON CARD ONE! after following the CSR's instructions, i told him card two was not working, and let's remove it also. then after installing card one by itself, install went fine. what exactly is going on that would make the card lose its binding?
