Play any movie from your Mac on Apple TV
Beamer is the AirPlay Video Player for Mac. It supports many movie and subtitle formats, so you don't have to convert your videos to an Apple TV compatible format. Simply drag-and-drop a movie on Beamer and it will start playing on your Apple TV!
Unlike Screen Mirroring, Beamer is specifically optimized for video playback at the highest quality. What's more, you can pause, forward and rewind using the Apple TV remote. No need to get up from the couch.
All common movie formats (AVI, MP4, MKV, etc.), codecs and resolutions up to 1080p are supported. Non-h.264 video is transcoded on the fly. Subtitles are supported, both embedded subtitle tracks and external subtitle files. Supported formats are SSA/ASS, SubRip/SRT, SubViewer and MicroDVD.






























, but I am using the Darblet with the 4520. I recommend it highly. Maybe you need a Thanksgiving Day present?
