Internet Explorer 8 does not support the new HTML5 tags video or canvas and neither do previous versions of the Microsoft web browser. It is likely that Internet Explorer 9 will be released with full or at least partial support for those tags.
Christian Adam has released an experimental add-on for Microsoft’s Internet Explorer that adds support for the video tag to the web browser.
The project is still highly experimental but it could become an option for Internet Explorer users who would like to (or have to) work with HTML5 video.
The screencast above explains how support for the HTML5 video tag can be added to Internet Explorer. The developer provides a setup on his website that needs to be executed. This file adds the support.
A demonstration video is linked from the blog post as well which can be used to test the support of the HTML5 video tag. It did not work for us in our Internet Explorer 8 browser.
It is likely that the developer will continue improve the Internet Explorer extension so that it becomes more stable and reliable.

I do not see a link do you mean the 4.8.6 The video element on the page http://www.whatwg.org/specs/web-apps/current-work/multipage/video.html
The title of the page used the video tag and this has cut off the rest of the article ;)
IE is the most unfriendly browser. IE8 has a lot of security bugs (most of them resolved with Microsoft patch), doesn’t support css3, the update rate to adapt at the latest web changes doesn’t exists.
I almost forgot to mention that his engine is loading the webpages like an old pentium I that runing with windows XP. :P
I HOPE with the version (IE9) that will come, IE to become more flexible, updated and FASTER.
