OK, here's the lowdown for people who have Streambox VCR but don't know how to 'peel' a hidden URL.
The process goes like this: go to the page that has the link, and save the link as a file (with right-click, and "save target as"). Then, take a text editor (Notepad, for instance), open the file, and copy the "http:" link found within (it is best to use the "search" function, as there will be a lot of codes in the text). Paste that in a browser window, and when the browser prompts you, save the file to your computer. Open that with a text editor, and look for a link with "rtsp://" (this time, most likely, this will be the only text in the file). That will be downloadable via Streambox.
Complications complement my life :).
