Is it possible to embed HTML5 videos from YouTube using the <video>-tag?

I want to embed a YouTube video on my web page and I want to use it with the <video> tag.

I suggest you have a look at http://www.youtube.com/html5 and take part in the BETA test. You can then look how YouTube is working with HTML5 and video. I'm sure you can find the answers to your questions by looking a bit at the sourcecode :) I will do that too :D
