You will be able to watch a YouTube movie about David Bowie just inside your Flash movie's htmlText field.
As you may notice, the adress of the external swf contains a parameter: video_id=2LTSFPkqZyg.
It seems l.swf is just a generic player application used by YouTube while a parameter identifies actual FLV streamed.
Fine - but I tried to replicate this functionality at my server and for whatever reason I am unable to collect any parameter sent this way to kind of a generic player I created.
The generic player works fine in case its URL with parameters is typed directly in a browser address field, but it fails to detect parameters while it's address with parameters is sent from SCR tag of htmlText filed of another Flash movie...
