What is the difference between two shortcodes for same playlist?

I'm going to make the WPMU Dev Video Tutorials a part of two protected pages...beginner and advanced. In the playlist shortcodes it gives an "either/or" choice of shortcodes, like [wpmudev-video group="pages" show_title="1"] or [wpmudev-video group="pages" show_title="0"] (show_title="0"] or show_title="1"]

What is the difference?
