You can't get html over flash you have to create a full flash website to get that effect or ...
make an animated .gif file in photoshop and set it as the background in DreamWeaver.
Google this for further info!
Make an animation for your 'moving background' and add your content over it
Contrary to the first response you received, you can place html content on top of an animaed Flash background. Here is an example: http://www.nedwebs.com/Flash/smiley.html
If you know Dreamweaver well then you should be familiar with working with divs and CSS. Just review the source code for the page to see how it was done
