Could you replace the codec section with at least an informative note
to this effect?  Something like,

"As of 2009, there is no single efficient codec which works on all
modern browsers.  Content producers are encouraged to supply the video
in both Theora and H.264 formats, as per the following example"

(If there is an older royalty-free format that is universally
supported, then please mention that as well, as it will still be
sufficient for some types of videos, such as crude animations.)
