Embedded Video Not Playing With IE7

Question

Hello,

 

I recently converted to IE 7and now my embedded videos I created on a website will not work.  They worked fine with IE6 and they still work fine with FireFox 2.0.  I have changed my security to the lowest level just to see if that was the problem and still no go.   I am using a javascript to call the video.  Any help will be most appreciated.  Thank you.
