It's all within the coding. For example:
<embed src="movieexample.mov" width="388"height="173" autoplay= "true"controller="true">
you want autoplay as true and then the controller as true or false, depending on if you want them to be able to stop, play, pause, and volume.
Let me know if this helps! If there's a problem, just let me know.
"I would feel more optimistic about a bright future for man if he spent less time proving
that he can outwit Nature and more time tasting her sweetness and respecting her seniority."
E. B. White (1899 - 1985)
