The videos are hosted on YouTube, and come with many of the standard YouTube capabilities, including the ability to view in Full Screen. Once you've started playing the video, you will notice the play controls appear at the bottom of the video where you can pause, set volume etc. On the far right of these controls there is a dashed square button which will allow you to enter full screen mode. Pressing your Escape key will bring you back out of full screen. Also, the YouTube button can be used to view the video directly on the YouTube site where you can access other viewing options.
