On a browser that doesn't support video this will use the fallback
content (OBJECT, etc) to instantiate something that can play the Ogg
file. On a browser that supports video and Ogg it will play the video.
On a browser that supports video but not Ogg, how do you then
instantiate a fallback that can play the Ogg file. Without JavaScript
and without providing an alternative source re-encoded in a different
format.
