To enable full screen playback, click on the Full Screen icon located at the bottom of the player.
Full screen video playback is available when using Windows Media Player, Flash, or H.264 in Internet Explorer. Full screen is not supported by the older versions of QuickTime or Mozilla Firefox. For Mac and iPad users, we recommend the H.264 format.
For users of Mozilla Firefox, when using the Windows Media Player (.asf) format, right-click (Ctrl+click for Mac) the video, select Zoom, and then select Full Screen.
