Tips for best results:
  1. Close all other programs before viewing a presentation.
  2. If you do not regularly restart your computer, it’s a good idea to do so to give it a fresh start. Many technical issues during video streaming can be solved by simply restarting your system
  3. Make sure you have your speakers or headphones on and system volume turned up. The presentation player itself also has a volume control in the browser window that you can turn up.

Online lecture FAQs

When will the lecture videos become available online?

Videos will be posted within 24 Hours after the class ends.

How long will the videos remain available?

All course videos remain accessible through the end of the semester.

What if I cannot view a video file, or get an error that states “unable to find or open a specific video file?”

There are two main reasons for getting an error message.  But first and foremost, try re-starting your computer!  Often this will fix many simple issues.

Make sure you are using the latest version of Media Player and Silverlight. Run the system tests linked at the top of this page.  (We strongly recommend you use the latest version of Firefox browser,  We do NOT recommend Internet Explorer.)

If you are using a computer at your company, their network may have a firewall that does not allow video through. Try contacting your company’s network administrator to confirm this. This may be the case if you can watch it from home, but not from a work computer.  Your system admin may be able to give you Proxy Server settings that can be changed in the Windows Media Player “Options” window, under the “Network” tab. Otherwise, try a personal computer that connects to the Internet via your home or cellular network.

If you have tried all of these solutions and you are still unable to view the video, contact technical support (see below).

Note: if you are viewing a live lecture, click on the logo at the top of the screen to enter the online chat room for that class. These are monitored by technicians during the live class, and can sometimes help you troubleshoot. You can also ask questions of the instructor, and interact with your fellow distance students.

How do I control the video?

Play and pause the video using the video controls at the bottom of the screen. Jump to sections in the video by moving the scroll bar located below the video window. You can also click on a slide thumbnail to jump to a particular slide in the presentation.

Can I enlarge the video window?

Click the icons at the top right of the screen to switch the video and slide screens, or to change the configuration of the screens.

Why do I have a lot of buffering or choppy audio/video?

Your internet connection might be slower than our recommended minimum speed of at least 750Kbps. Make sure your system passes the speed tests, linked at the top of this page. Also, try turning off any anti-spyware software that you may have running.  Close all other programs and windows you may have running.  Restarting your system can often solve issues that come up.
