Why not Xvid? [was codec optimization]

[Zvi Devir]

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.
