In IE it is dropping down but you aren't seeing it. Since it's contained in a div that is only 22 pixels tall you only see the top 22 pixels of the 200 pixel high flash video. If you right click on your text below the menu in each browser you'll see that in Firefox you can see the entire Flash file but if you do it in IE you'll see that it's cut off. You'll have to use CSS and make that div 200px high and just have it overlay the text beneath it.
