I understand that you are not able to play the videos in the MATLAB fundamental course.
You can perform the following troubleshooting steps to resolve the issue:-
1) Check if the Flash plugin for the browser is enabled (this is required for the videos to play).
2) If this does not help, try using a different browser and/or disable active add-ons on the page (if any).
3) If none of the above is applicable, it could be due to a firewall issue. Try launching the course from a different network (like home internet, instead of work).
