azap and the like will find all the streams,not just the watchable  
ones. If you find that a strem is not watchable video couldn't you  
just save it to a file and look at it with various tools (hex editor,  
or try to interpret it as an image etc.).

Of course if the stream is encrypted, you will have to mention it in  
a phone call, then email it to somebody, then go ask Mr. Bush what  
the content was :-)
