Using jQuery Flash Plugin?

Using jQuery Flash Plugin?

I've tried two jQuery Flash plugins so far (Flash and jMedia), and neither is working, which makes me think I'm missing something in terms of the correct way to implement them.

Here's my html for using the Flash plugin (found at http://jquery.lukelutman.com/plugins/flash/#faq ):

<div id="Show_FZ_Demo">Click to see the demo video!</div>


...and here's my jQuery code:

$(document).ready(function()
{
   $('#Show_FZ_Demo').flash(
       { src: 'http://localhost:8888/images/FZ_Demo.flv' },
       { expressInstall: true }
   );
   
});


The Flash plugin inserts an empty space of the correct size to display the video into the page - but it doesn't display the video.

How can I correct this?

Thanks very much in advance to all for any info.
