IE Iframe Bug - Web Player

Hi just found a bug and was able to reproduce it over on few pcs.
Here it is

I am trying to load a divx file in a iframe and halfway through i am pausing the player and loading a other div in its place with a form asking the user to continue watching or fill out a form with comments on the video. Everything works fine in Firefox but in IE when the user clicks to continue watching the web player bugs out and cannot unpause or even play the video if i manually click play.
I am using javascript to control the player and hide and show the divs.
Also if you visit the link directly without a iframe it works in both browsers so i would say its the iframe causeing this problem.

Please help me out i been pulling my hair out for over 1 week now
