Videos and Slide Shows

If you have trouble viewing a video/audio or slide show, check this page for more information.

For best results, view on a Windows 98, 2000, or XP PC with Real Player version 8.0 (or later) and Internet Explorer 5.5 (or later) or Netscape 7 (or later).

Video/Audio Troubleshooting for PC Users

1. Check that your PC meets these minimum requirements:

2. Does RealPlayer launch when you click on the presentation? If not, you may need to download the free RealPlayer from the Real Audio web site.

3. Do you have a firewall? A firewall is a system designed to protect private networks from unauthorized access. Depending on how a firewall is set up, it might block or affect the quality of streaming audio or video. Your network administrator will generally know if the firewall will affect video playback.

4. What is your connection speed? A modem of 56 Kbps is a minimum requirement-a high speed Internet connection is optimal. All presentations are optimized for the best results for a given connection speed. Dial up connections may default to audio only presentations; you'll hear the presentation but won't see the video.

Even with a higher speed connection, actual connection speed can vary depending on the time of day and level of traffic on the internet. As network congestion occurs, playback quality can degrade or become unstable.

The more bandwidth required by a streaming file, the more likely that network congestion problems will occur. Better quality is possible with higher bandwidths, but maintaining that bandwidth for an extended period can still be a problem.

Video/Audio Troubleshooting for Macintosh Users

1. Check that your Macintosh meets these minimum requirements:

2. Do you have OS X? OS X users may experience limited functionality. You may not have control over the video or bookmarks.

3. Does RealPlayer launch when you click on the presentation? If not, you may need to download the free RealPlayer from the Real Audio web site. The presentations do not work with QuickTime. If QuickTime launches, close it, and then download RealPlayer.

4. Do you have a firewall? A firewall is a system designed to protect private networks from unauthorized access. Depending on how a firewall is set up, it might block or affect the quality of streaming audio or video. Your network administrator will generally know if the firewall will affect video playback.
