The above video tag comes from [dev.opera.com...]

On my local machine, the tag plays well on all latest browsers IE9, firefox7, opera10 chrome and I use WAMP server ver 2.1.

Now after uploading them to my website, only Chrome and Opera plays the videos exept IE9 and firefox.

Are there some settings that I need to change on my actual website server or what?
