I am trying to get a Comcast Digital Converter received in Illinois to work on a Comcast svc in Florida. When connected it shows it is downloading data but when it reaches 100% I get a msg svc has been terminated and contact Comcast. When I remove the device I still have analog svc and limited channel selection. Not sure why this occurs? The Florida Comcast account is not in my name so I am looking for an independent solution. Thanks !
