I put some wmv files up on the web and wanted it so that you click on them and they play.  However in Chrome they do but in Firefox they download first.  I need a way to make them play on click in all browsers because I'm certain some people won't have a plug in such as that in my Chrome.

Suggestions are more than welcome.  

I started out with a huge mov file and now have a low res wmv and higher res wmv file of the movie.

thank you.
