video source?

I am attempting to locate the raw address behind a .swf video file, I have some experience in the past gaining media streams for online radio utilizing url snooper, but when I attempted to capture the video's address I do not see anything but http redirects and GET commands. I've also been able to secure quite a few xml files in hopes of locating the direct stream address, but my efforts have been futile. I was hoping to be able to open the stream in an external application, I have attempted to utilize several firefox add-ons as well, but have had the same trouble.

Does anyone have any suggestions that can help me out here?

Thanks,
