When the user clicks on a thumbnail it activates swfobject and simple modal. It opens the modal and loads the swf into the modal. The swf is loading an flv. I used Flash to do the flv -> swf thing.
In IE7 there is an audio echo when it's being played in the modal, but not when just watching the swf from the server. I have sucessfully used this same code on several sites but never encountered the echo before. There is definitly only one swf loading.
Any ideas?
