I have a flash video player that I would like to embed in other pages, so I created an iframe to do this. It has to be an iframe because it depends on other swf files that get loaded into it (plugins).
The weird thing is the video does not play when loaded inside the iframe, but if I go to the html source and cut and paste the tag outside of the iframe it works.
<iframe width="500px" height="500px" src="http://somedomain.com/embed.aspx" ></iframe>
Got it working by adding come css to the html page containing the flash player. It seems the absolute positioning made all the difference.
