Loading videos on the fly using video.js

Video.js doesn't have a lot of documentation when it comes to doing really cutom stuff. For example, loading videos using a partial postback and changing the subtitles. Fortunately I'm not the first one to run into this problem, and I found this link that shows how to do it. It works in Chrome and Firefox. IE 8/9 is different because it's Flash, so you have to check the browser type before executing the code.
