I Really Need Help

[Levitt]

Hello, my name is Steven, and I am a magician.

My website is having troubles, well... One page. Which is this page:

http://stevenlevitt.co.uk/index.php?/site/film

When trying to "Stream" the video. It looks fine in Internet Explorer, but a total mess in FireFox.

Please can someone help me with the coding, in order to fix that page?

Sorry if this is the wrong part of the forum, I am not a designer, and I am in need of a little help.

Thank you in advance,
Steven

It looked OK to me in Firefox. What is messed up? The page layout or the video window size or the playing of the video?
