Roku Activation for TV Channels

I use only Roku for TV and have a variety of channels I may select from besides Netflix to watch shows on. eg National Geographic, PBS and AETV Each selection requires submitting a code online to activate the channel, yet for some reason I am unable to do this with AETV Is there a reason Cox is not on the list of Providers? There seems to be hundreds to choose from, but because I cannot find Cox on the list, I am unable to unlock that channel Please take this as a request to get added to the AETV list. I see others with similar requests and have to say it makes you look quite a small player by not being on those Provider lists. Century Link is on those lists, yet you are not........... Thanks in advance
