Have you tried any of these rtmp flash videos?  I installed Real and it 
didn't find the one I wanted.  It did find a youtube video, but flashgot 
already does that perfectly.

These darn things are embedded in the flash code and the browser doesn't 
even know they're there.  Since Flashgot (and probably real) are 
triggered by the browser finding a stream, they don't work.

rtmpdump would probably work, that's what it's designed for - *if* - I 
could figure out what url to give it for the stream.
