This might be a simple question but I am not an apple guy. We have an apple tv connected to projector that the Sr. Pastor uses air play with for slides and what not. that works fine but before he gets there I would like to be able to get it started and have Bible screen playing rather than the latest and greatest movies and tv shows. Roku has a channel that can be added to their devices but I cannot figure out how to get the bible screen app even on the apple tv let alone run. I would like to do this without using air play so that the Sr. pastor can work with his ipad in his office until the last minute. Any ideas would be appreciated.
