How do I watch videos?
	Click on a channel in the left pane that has some videos to watch (the channel name should be in yellow text and have a number >0 in parenthesis following it). A video should start to play in the right pane.
How do I change videos within a channel?
	In the right pane you should see a row of thumbnails below the current video. You can click on one of those thumbnails to watch that video. Just to the left of the title of the current video may appear a left and/or right arrow (they only appear if there are videos to watch before or after the currently playing video). Click on these arrows to go to the next or previous video.
