These clips are recorded in the newest format, RealPlayer 9 (better quality). RealPlayer 8 needs 2small files added to it to bring it up to date to enable it to play new and older movie clips. When your RealPlayer 8 asks you if you want to "Autoupdate" click yes and let it install these files to your RealPlayer. This will not upgrade you to the "RealOne" player (which some people are experiencing problems with) it will simply upgrade the older reliable RealPlayer 8.
Good luck.
