Sorry for jumping ahead, but this something I really don't understand.
Let's assume that there are currently a few valid US patents on JPEG,
MJPEG (There are probably more) as well as for MPEG4.2 (xvid divx
wmv1
and many more are MPEG4 part 2 implementations). My question is, so
what? A patent is a territorial legal being -- it is valid only
where it
was granted. Even if JPEG is covered by hundreds of active US
patents,
and some unenforceable EU patents, it has nothing to do with countries
in which the OLPCs will be distributed, since those patents are
invalid
there.

x264 requires more computation power for decoding compared to xvid.
Yes, Xvid requires half computation than any other codec, in my
experiences.
(using Windows XP, ffdshow+Xvid, Sempron 2800+, mostly to record TV in
real time).
With any other codec I reach 100% of frame grab, 640x480, 29,97 fps,
RGB, deinterlacing, with 60% of CPU time.
Benjamin Franklin was right: patents sux!

Yes, but surely the point is *why not use theora and vorbis* ? Shouldn't
we be supporting completely free standards wherever they are available ?
Several million laptops with ogg theora and vorbis support by default,
would provide a lot of leverage.
