Embedded Windows Media Player <OBJECT>

Hey,

I'm having trouble with my embedded Windows Media Player. What I want to do sounds simple. All I want to display is the visualizations and some images to the right to replace the controls. I've found the HTML and javascript for both of these, and they work perfectly for me. Meanwhile, my friend is viewing it using Mozilla Firefox BETA 2 and WMP 11 BETA 2. Instead of visualizations, he can see the WMP controls and furthermore, the buttons won't work.

That's the page it's on. If anybody knows a solution, please help me :). I would really appreciate it. You can see all of the HTML/JS yourself, just view the source.

Thanks in advanced,
Halting
