These clips require that you have a program that can view "streaming video." You can use an up-to-date version of Microsoft's Media Player, mPlayer2, or a RealVideo player which you can download for free from the Real website. Click on the icon below to get your free player from the Real website.
After you download the self-extracting ".exe" file, run it by locating it in "My Computer" and double-clicking on the file. The RealPlayer should install.
