           Playing 
              QuickTime Movies:
          
         
          
         Many of the pages on this site include video or virtual reality 
              clips that require the QuickTime movie player. QuickTime is supported 
              by Macintosh, Windows, Windows 95/NT platforms.
         
        
         
          
           If you aren't able to watch movies, 
              there are two possibilities:
          
         
         
        
         1) You don't have the QuickTime player (or a recent enough version 
              of it) installed on your computer. To download the player, visit 
              the
         
          QuickTime 
              download page
         
         .
         
        
         Before you download, be sure to bookmark this page, since you will 
              need to quit out of your browser if you decide to install the QuickTime 
              plug-in.
         
        
         2) If you are using a PC with Windows Media Player installed, you 
              may have WMP set as your default player. This means that WMP will 
              launch, but might not play the files, or might play them improperly. 
              If this is happening to you, please see our
         
          QuickTime 
              on the PC help
         
         page.
         
        
         
          
           Once you have the player installed:
          
         
         
        
         • Remember that QT movies can be large files (up to 2 Mb) 
              and may take several minutes to download, depending on your connection.
          
          
         • To play QT movies, use the control buttons at the bottom 
              of the movie frame.
