I recently added BBCAmerica so I could get DR Who. When I go to the channel and click on an episode it wants me to go to a computer or mobile device and enter a supplied activation code. What gives? Is this a one time thing? Am I paying extra? Is DR Who on anywhere else?
The BBCA app is tied to a cable/satellite subscription. There is no stand-alone BBCA subscription.
Not sure if it's available on other services, but you would almost certainly need a subscription. Amazon Prime has a few episodes available for free, but most are rental/buy.
