Yochai,
It is not just that link or your machine, it looks like the whole http://video.esri.com/ site might be down right now. It's returning an error for me
"NetworkError: 500 Internal Server Error - http://video.esri.com/"
I would try again later, or maybe tomorrow. I'm not sure who should be emailed about it, but maybe Timothy Hales knows and can let the appropriate staff know?
