I would not recommend this app. Its Slick with the interaction but it streams via AirPlay mirroring and not AirPlay resulting in a choppy and lower quality playback. If you arent interested in steaming to your ATV this will do what it says. If you want to stream video to your ATV this is not the app for you. I now use something from Ractor but there is more out there.
