question

Do you load their NinjaVideo helper application and also have divx software installed on your machine?

I've done both and it still does not work

There are links to follow on their forum, accessed via the report video link, that will give you steps to check to see why it might not be working for you. Make sure your java is updated, and you have the newest version of your browser first, then follow those links, but without actually reporting the video (if all the videos don't work, the problem is on your end).
