      4. Why am I asked to upgrade my media player?  
     
    The video content was formatted using newer technology than is not supported by your current player. To get acceptable playback, you should upgrade to a newer version of the player.
     
      5. Why doesn't the demo play in my Netscape browser if I have a Real Player installed?  
     
    Real Player plugin must be installed after Netscape browser installation is completed. We recommend you to re-install or upgrade your Real Player. To download the free Real Player, click here.
     
      6. Where can I get more specific Real Player help?

      7. What bandwidth do I choose to play the video?  
     
    For presentations that offer this selection, choose a bandwidth according to the type of Internet connection you are on. If you are using a 56k dial-up modem you should select a low bandwidth to view streaming video content. If you are using a cable modem or DSL connection, a mid-to-high bandwidth is your best choice. Please note that some DemosOnDemand content requires a broadband connection (at least cable modem or DSL) to stream correctly, and no 56k/modem choice is available.
     
      8. Why does nothing happen when I click on the "play" button?  
     
    If you get a DOD player window, but you don't see the video, it is possible that the video may be buffering. Please allow a few seconds for it to load and begin streaming. If you are waiting for a significant amount of time, the following reasons may be why nothing is happening when you hit the play button:
     
  • Either the computer, operating system and/or Internet connection do not meet the player's system requirements.
  • You may have selected the wrong bandwidth to view the video. Select low bandwidth for 56k modem connection and medium to high bandwidths for cable modem or DSL connections.
  •  
      9. I am getting a message prompting me to login to a realm proxy with IP address.  
     
    In some cases your network administrator may have blocked your access to the streaming server which delivers the Demos On Demand video content, or may require you to configure the proxy settings in your media player in order to stream video through your firewall. Contact your network administrator to determine the settings for your organization.
