I have called Comcast at least 6 times asking what I thought was a simple question yet I received many answers. I hooked up the DTA (Digiital Transport Adapter) box on my TV. I used the TV controler to put the Tv on channell 3 and then I was told to put the TV controller away and use the controller that came with the DTA box. Problem, when you use the DTA controller the stations that are blocked on the TV now show. There is no "Menu" button on the new DTA controller to program "Parental Control" and Comcast said there is NO V-Chip in the new DTAdapter. I don't allow my chidren to watch MTV, Jerry Springer, Comedy Central etc, and now if I want the Disney Channel, syfi and others, which I'm paying for I can't have them unles the new DTAdapetr can block certain stations.
What am I missing here? No V-Chip or Parental Contol availabliity with the new Digital Transport Adapter??
Is this true??
