I did the same and ended up with the same result. That's why I wanted to
get rid of the pmvs[]! The (stupid) XVID codec sets pmvs[] during SearchP,
so if you change vectors later (e.g. because you use GMC with different
vector than search told you), you have to modify _all_ neighbouring
pmvs[]. Same for INTRA decision, btw. I have no idea why it did work until
now.
