·WOW Internet and..
Have them recheck the authorized channels for the card. I just upgraded one of my TivoHD's (had 2 single stream cable cards in it) to a newer Premiere. I stopped by the local WoW service center and they gave me a multi-stream card for it, but once it was installed and paired, I couldn't receive any channels. They dispatched a tech that showed up and told me he thought it was fixed before he showed up, and when I did I was able to get all of the channels I am paying for. It sounds as if, like me, they haven't authorized the channels for that card yet.
and the hits just keep on coming.........
