What's the difference between the Macromedia Flash and Shockwave Players?
Flash and Shockwave Players are both free web Players from Macromedia. Together, they bring you the best rich media content on the Internet. Each has a distinct purpose. Flash Player delivers fast loading front-end web applications, high-impact web site user interaction, interactive online advertising, and short to medium form animation. Shockwave Player displays destination web content such as interactive multimedia product demos and training, e-merchandising applications, and rich-media multi-user games. Through Xtras, Shockwave Player is also extendable to playback custom-built applications. When you download Shockwave Player, it automatically includes Macromedia Flash Player.

So, if in doubt, just download the Shockwave player.
