        This module plays a video on an AppleTV device. Note that
        AppleTV can be somewhat picky about the server that hosts the video.
        Tested servers include default IIS, default Apache, and Ruby's WEBrick.
        For WEBrick, the default MIME list may need to be updated, depending on
        what media file is to be played. Python SimpleHTTPServer is not
        recommended. Also, if you're playing a video, the URL must be an IP
        address. Some AppleTV devices are actually password-protected; in that
        case please set the PASSWORD datastore option. For password
        bruteforcing, please see the module auxiliary/scanner/http/appletv_login.
