I just got this unit and at first wasnt getting hardly any of the channels, let alone HBO. I called Cox and they sorted it out, started receiving all channels apart from HBO. They et up for someone to come out tomorrow morning to have a look at it. She also said i should call tivo ,see what they say. I did and they said it was a Cox cable problem and that my billing code wasnt inputted correctly. I checked with someone over at Cox and he said everything was right on their end. The guy at Tivo said this was a common problem, so i was wondering if anyone here can help me out? i just get the message that i am not authorized to view this channel and to contact my cable provider.
