IE9 HTML5 video support
I am working with a client to try and get their video player working. It seems to work in everything that I can test in except IE9. I'm using videojs (I've tried other ones and the same result).
It seems to be that it's one of 2 things. A setting on their IIS server. Or the video file isn't encoded correctly.
