Camtasia Studio Video on webpage

Having one heck of a time taking a Camtasia Video and putting it in a web page to automatically start when the page is loaded.

Camtasia can produce a wide variety of formats but does anyone have any idea of which one works best with Corel?

I do have a sample that I finally got to work and it's at http://algebramath.net but that was created with powerpoint and video recorded with Jing (produced by the same people that make Camtasia Studio, only free).

I tried to make a swf but the resulting file requires the preloader for an "index" page that is written in html by Camtasia.

Anyone have success with say an mp4 file?
