A problem playing Flash video in Windows

Upgrading to the latest version of FireFox and Adobe Flash Player seems to solve the problem described below. If, on your system, the problem persists after making these upgrades, please submit a trouble ticket.

In implementing the Flash video player solution, it came to our attention that there is a general bug that causes Flash videos to malfunction. In the most common form of the problem, the video starts in silence and plays for 2 to 4 seconds and then it stops playing altogether, though the video appears to continue to load. The problem is intermittent and sometimes everything works fine or can be temporarily alleviated by restarting your computer. However, the problem returns.

One of the difficulties with an intermittent problem is that almost any change may APPEAR to have fixed the problem simply because the problem is intermittent and it may just happen to be in its working phase when tested after an ineffective fix is attempted. Thus there are bound to be zillions of APPARENT solutions experienced that the user later finds out didn't really work. Because discussion forums of bugs gather together the experience of large numbers of users, if only a small percentage of the apparent pseudo-solutions are posted before they are found to be ineffective, the result is that many false solutions appear on the Internet. Thus, we had to wade through all sorts of illusory solutions we found on the Internet in addition to the apparent solutions we created by experimenting.

Note: This means that most of the solutions you will find posted elsewhere will only work for a period of time and then the problem will resurface. If you find a solution that seems to work, please test it for a few days. If after a few days of testing (including visits to that problematic page), your solution still works, please let us know. (Post a comment on this page or submit a trouble ticket.)

The two solutions to the Flash/Firefox bug.

One is to use Internet Explorer to view pages with Flash video. Unfortunately, this option may cause other problems using MyLessonClub.com. So the other option that works is to roll back the Adobe Flash Player plugin to an older version.

How to roll back the Adobe Flash plugin.

  1. Follow these directions to uninstall flash
  2. Download an older version of Flash (try 9 first)
  3. Follow the directions to install flash
  4. Restart your machine
  5. Return to the member's area and test
