      7. Why do I get a message that I have no Media Player codec installed when I launch a demo?  
     
    DOD demos require special codec (Windows Media Player component) to be installed on your computer, which may be missing in the default setup of your media player. This most often occurs if you are not using the latest version of WMP.

      STREAMING AND BUFFERING:  
      1. Why do I get a player window with no loaded video and a message stating "Buffering. Please wait."  
      2. Why does the demo frequently pause and buffer before it resumes play?  
      3. What bandwidth do I choose to play the video?  
     
     
      1. Why do I get a player window with no loaded video and a message stating "Buffering. Please wait."  
     
    Depending on your connection speed, it may take a few seconds to load a segment of the video content in order to begin streaming.  If streaming does not begin after 30 seconds, you may have an older media player, and you should consider upgrading by following the instructions above.
     
      2. Why does the demo frequently pause and buffer before it resumes play?  
     
    In some cases, firewalls block Universal Datagram Protocol (UDP) traffic, which is the protocol required to play streaming content. In those cases, the Player is forced to use the HTTP/TCP protocol, which causes buffering and pauses when there is network congestion.  If possible, contact your network administrator and request that UDP traffic be allowed through your firewall, as this is the best means of delivering streaming video over the internet.
     
      3. 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.
     
     
     
      VIDEO AND AUDIO PROBLEMS:  
      1. Why does nothing happen when I click on the "play" button?  
      2. Why the screen video is choppy and/or doesn't play back in synch with the presenter video.  
      3. Why I am unable to see either the presenter video and/or the screen video.  
      4. Why I can see the demo but am unable to hear it.  
      5. I am getting a message prompting me to login to a realm proxy with IP address.  
      6. I'm having video problems (i.e. green or pink lines on the video, blurriness, etc.)  
     
     
      1. 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:
     
  • You have an old version of Windows Media Player and need to upgrade (i.e. earlier than 6.4). Click here
    to upgrade.
  • 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.
  • You are receiving a specific error message from your Windows Media Player, click here for more information.
  •  
      2. Why is the screen video choppy and/or doesn't play back synchronized with the presenter video?  
     
    This is a very common problem with Windows Media Player 8. Please upgrade your player to a later version by clicking here.
     
      3. Why I am unable to see either the presenter video and/or the screen video?  
     
    You may not have the correct codecs installed in your Windows Media Player. Either download the latest codec package (for WIN XP click here), or re-install Windows Media Player here.
     
      4. Why I can see the demo but am unable to hear it.  
     
    First, double-check that your speakers are on. If you are able to hear other content, then you make not have the correct audio codecs installed on your system. Either download the latest codec package (for WIN XP click here), or re-install Windows Media Player here.
     
      5. 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 DemosOnDemand 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.
     
      6. I'm having video problems (i.e. green or pink lines on the video, blurriness, etc.).  
     
    Check for updates for your video card driver and DirectX from the Windows Update page. If that doesn't solve the problem, turn down (or turn off) video acceleration.
    To do this in Windows Media Player 9 Series, go to the Options dialog box and look for the Video Acceleration option on the Performance tab.
    ** Note, in some instances, clearing the Start player in Media Guide check box on the Player tab of the Options dialog box might resolve video problems.
