    I wrote a proof of concept P-VOP motion search algorithm for xvid 
which was a big hack and only worked under win32 in August.  I was 
waiting on Skal to get his "slave threads" into CVS before I came up 
with a workable cross-platform implementation.  Hack diff is here:

    However, Radek Czyz also wrote his own motion search that worked on 
PVOPs and BVOPs in December.  I am unsure what the status is of his work.

    (These are both on the xvid-devel list, not CVS)
