I have been trying to get this working and no luck. Infuse free app on aTV4, shared late 2012 iMac running latest El Capitan, all over an Airport Extreme current gen. I have the Movie folder on my iTunes directory set for file sharing in the appropriate control panel. I have typed my user name and password into the setup on Infuse. It just sits there with the spinning sphincter wheel telling me its checking the connection. WTH?
