So, I was willing to watch some videos on Screenr and to my demise they weren't playing right in Chrome, and besides I really like to watch videos as stand-alone files.
And I couldn't find any way to just download them! It's not as easy as Vimeo where you can quickly steal the URL from the HTML5 player's <video> tag.
Lucky me, I'm stubborn. I disassembled the flash-based player, saw that it calls some ASP.NET web service through a SOAP interface and from that it gets an URL (http://www.hurl.it/hurls/0043f3b6d4711378f4afd08c41b67949c6474c17/c7d82ffad23c3ff4bb2d4bc0703cc33d4a001b93).
Lucky you, I put that same logic into a bookmarklet,
