Firefox and the Front Page Windows Media Plug In

I'm using FP2003.
I manage http://www.leyla-najma.com and the client requested a video clip
introduction on the homepage. I created a small video usine the Windows
Movie Maker and then embedded the file on the page using the Windows Media
plug in for FP. The page works fine for IE and Netscape but the video is not
displayed by Firefox 1.04. Does anyone have a work around or know about this
issue, or can recommend some other alternative other than the Windows Media
Plug in for FP to embed the media file?

Thanks in advance,

Dan
