Issue with loading swf with video

Here’s my situation. I’ve got a homepage. On it are three buttons. Each will load a different swf to the stage. I’m using a MovieClipLoader. The problem comes when I load the swf with a flv - all I get is the icon for a movie flickering on the stage.

My current workaround is to have the video appear in a new browser window- it works, but it’s less than ideal.

I’m working with Flash CS3, coding with AS2.

I do so little work with video, I don’t even know quite where to begin to troubleshoot this. Any help will be, er, helpful.

thanks
