For video, you could use an embedded Flash movie hosted on YouTube:
1 <video controls>
2 <source src=best-video-ever.webm type=video/webm>
3 <source src=best-video-ever.mp4 type=video/mp4>
4 <!-- fallback content: -->
5 <iframe width="480" height="360"
6 src="http://www.youtube.com/embed/xzMUyqmaqcw?rel=0"
7 frameborder="0" allowfullscreen>
8 </iframe>
9 </video>

This way, users of older browsers, such as IE 6-8, will see a YouTube movie (as long as they have the Flash Player), so they will at least be able to see the video, while users with modern browsers will get the full native-video experience. Everyone gets the content, then, which is what your website is there for, after all.
