Solution: These Web Lectures are intended to be viewed on a monitor set at resolution 1024x768 or higher. If your monitor is set at only 800x600, the slides will be too large for the screen. To choose a higher resolution on a Windows computer, right-click on the desktop, click on "Properties", and then select the "Settings" tab. You will see a slider that enables you to select different resolutions. 1024x768 or anything higher will be fine.
Solution: The RealPlayer plug-in is required to view these Web Lectures (either Real Player 8 or RealOne Player will work). If you have not installed it on your computer, go to http://www.real.com/ . Click on "Download RealPlayer," then on "Download Free RealPlayer".
Solution: You may have an old version of RealPlayer (older than version 8) which cannot play newer files. The solution is to download the latest version of RealPlayer as described above.
Solution: Either you are connected to the internet via a slow link (eg. modem dial-up) or there is a lot of congestion on your network.
If you are connected via a slow link then you might get better performance by selecting the "audio only" version of the lecture.
Another thing to try is pre-caching all the slides before starting the lecture. You should pause or stop the video and click on the "PREVIEW SLIDES" button, wait until all the slides load, then resume viewing the video.
If you are constantly plagued with network problems, you may always download the lecture and view it locally from your computer's hard drive.
Solution: This is a known problem with the plug-in video version under Unix. If you are using Unix then you should view the "detached" version of the lecture, which will display the RealPlayer video in a separate window.
If you experience this problem in Windows using RealPlayer 8, you
may need to change settings to enable RealPlayer to link to
external pages (change settings by right-clicking on the video window).
