And I would agree, as I was stacking a disengenious chain on top of
Robert original one.

I'll see if I can get the numbers/video for you on that (and I'll do
it off list, for th sake of the whatwg mailing list :-) . The trick is
starting from the raw upload.

Ugh, I made a mistake, the google i/o demo was more a demo of the
video tag, I think the embedded video is 264 in that one. I'll find
some of the theora examples and send them to you. They are just
examples, yt is held back by client compatibility.

I tried funding dirac a while back, to some good end, and we provide
students, but here's the challenge: Can theora move forward without
infringing on the other video compression patents?
