// Video Magic JS by Anders Eskholm (c) 2007 - anders@eskholm.dk

// README
//
// Renders inline video (embedded) from Streetfire.net, Youtube.com, Vimeo.com, Google Video and MSN Soapbox
// Searches given page elements for links/urls to above mentioned video links, and replaces with embedded video
// This version is custom for Benjamin Magazines online (http://www.benjamin.dk/)
// Modify as you like, but keep original author comment, please.
//
// Replacing only if any valid link is present. Searching both plaintext urls and anchored links.
// Adding proper event listener to onload chain, for script to run at page load end.
//
// Enjoy.
