same author, reply about YouTube / Ogg/Theora comparison

"The test isn't representative of the types of videos we
produce as the resolution we use is significantly higher
than a typical YouTube video. Theora does not perform as
competitively with H.264 on large videos as it lacks support
for several encoding algorithms that are beneficial in this
regard. H.264 Main and High profiles can be significantly
more advanced. "
