Did the Allen Media Group channels leave Cox?

Hi there. I am sorry that you are having issues with those channels. I did pull a quick query of those particular channels, and they are still in our channel lineup cards, as of the recent update from this month. Does this occur on all of your boxes? You mention it is dead air, so you do not get an error message saying its off air or channel not available? Have you tried any resets to see if it will help? If you have any account-specific questions, please email Cox.Help@cox.com with your full name and complete address, and we can go from there.
