On my commercial account, it has appeared as 9511, but is in RED. It has not mapped down to 209, or 4xxx, and cannot be selected. I get a "subscription" error 014.
I had this same issue with the Gang of Seven that were added a few months ago. It was about a month before they were selectable on my commecial receivers. It took many calls and emails to their commercial support dept.
My opinion is that they simply didn't add those channels to the authorization database for the package to which we subscribe. I hope this will not be happening with MSNBC, as well.
