For some odd reason if you want to watch the following video from Microsoft at the Channel 9 site about the IE 9’s support for standards and interoperability, you are prompted to install Silverlight.
I just thought I'd post this to show them how it's done. The quality of the Ogg file isn't the greatest so apologies for anyone using Firefox 3.5 or Chrome. Update: I removed the Ogg version of the video to cut back on bandwidth usage.
