DH does not has a flash server for streaming flash videos.
This will depend on how you create the files as Adobe flash can embed the flv file into a single swf file but is meant for smaller files.
Create a loader swf file that contains an image (convert to button) and this code:
function player(event:MouseEvent): void
var request:URLRequest = new URLRequest("http://www.example.com/example.swf");/*edit this link to point to your movie's swf file and remove everything after the semi colon on this line just in case*/
var loader:Loader = new Loader()
This will allow the viewer to see your web page without downloading the video until they click on the image(to be nice to dial up users). Make sure you convert the image to a button.
As I mentioned above streaming is not possible.
I hope this helps,
