Facebook (which seems to be supported?) fails with "Cannot parse data".

This presumably is because of privacy restrictions on that video: probably a good idea to have a "Can't read because I don't have permission" on it, I suppose.

Now, it reports the same message as Facebook: The page you requested cannot be displayed right now. It may be temporarily unavailable, the link you clicked on may have expired, or you may not have permission to view this page.. If you can see it when login, using the --netrc option (or --username and --pasword) should work now.
Thanks for the report.
