Firefox doesn't show it, Internet explorer does but won't play it properly

Good day,

I have a test page for a website I’m currently working on, there’s a video player on it that shows itself on internet explore but doesn’t actually play the videos and on Safari or Firefox it doesn’t even show itself.

The webpage is located at: http://viloda.com/videoindex_portfolio_rtvnh.html and I think there’s something wrong with the HTML. There’s probably something wrong or/and missing but I can’t find what.

So I was wondering if perhaps one of you could help, thanks for reading this over.

Edit: The Video Player works perfectly fine locally, so the player made in Flash can’t be the problem, I think it has to be code.
