do Sintel make bad image for theora?

Hallo all,
there is sintel online premiere up today http://www.sintel.org/ . But
oggtheora video is every thing but not gut. I downloaded 720p version
but IMHO some times it looks  for me like scaled 480p. In my experience
theora can do better, or em i wrong?

strings Sintel.2010.720p.Theora-VODO give me fallowing:
ENCODER=ffmpeg2theora-0.24
Xiph.Org libtheora 1.1 20090822 (Thusnelda)

Screenshots are in attachment.

PS: May be it will be good idea to make ffmpeg2theora write to ENCODER
section encoder parameters too?
