MSNBC offers many videos on their site, but hide them behind code that restricts their viewing to users of Internet Explorer 6 and Windows Media Player 10, both of which are Windows only. Thanks to Flip4Mac, Flip4Mac forum member andgarden, and especially to a Javascript guru that goes by the name of Void, Mac users can now watch these videos in Safari or Firefox.
Create a new blank bookmark entry, and name it MSNBC video fix (or whatever you like). For the URL portion of the bookmark, copy and paste the following code:
javascript:(function(){var%20as%20=%20document.getElementsByTagName('a');for%20(var%20i%20=%200;i%20%3C%20as.length;%20i++)%20{if%20(as[i].href.substring(0,19)=='javascript:msnvDwd(')%20{var%20b%20=%20as[i].href;var%20temp%20=%20new%20Array();temp%20=%20b.split(%22'%22);as[i].href='http://msnbc.msn.com/default.cdnx/id/'+temp[15]+'/displaymode/1157';}}})();Mac OS X Hints
