HTML5 Video and Fullscreen

I've just been experimenting with the HTML5 video tag and just realized that neither Google Chrome nor Opera allow you to fullscreen the video (OGG) but Mozilla Firefox does if you right-click the video and select Full Screen...

And what of Internet Explorer 8? It doesn't even render the CSS properly, let alone the video!

I found this great article that shows a code sample of how you would implement captions/subtitles/other based on the position in the video. Pretty cool no? http://randallagordon.com/blog/2009/07/19/jaraoke-html5-audio-tag-demo/
