(There's no video for RealPlayer 5.0 Beta 1 yet. Please contribute to MR and add a video now!)
RealPlayer version 5.0 Beta 1 (expires after 60 days) so it's totally useless, in practice. Anyways, to use it today, you have to set your computer clock back to any date before the month of October, 1997.
Note: This installer puts a plugin under Microsoft Internet Explorer and Netscape Navigator, plus extensions in your System Folder > Extensions which are used by the RealPlayer application.
