Step 1: Create a Flash movie record (NOT A CONTENT ELEMENT!)

Create a new record using the “create new record” button or via the “new” command in the context menu (click on the icon next to the page title in the page tree).

Choose “Flash Movie” as shown in the picture below

Now fill out the Flash movie settings

Step 2: Create a “Flash Movie” Content Element

Click on the "create new record" link, to add a new content-element. In the next screen click on the wizard link under “Pagecontent”.

At the “New Content Element Wizard” select the icon “Flash Movie” at the bottom of the page.

Now add the previously created “Flash Movie” record to the content element and you're done.
