Well..  When I show it in Mediaplayer, one of the frames is indeed green,
but I could not manage to reproduce that using FrameAnalyzer..

Actually there was a lot of MVs in frame 4, thus all the pink blocks in frame 5
Frames 1-3 shows nothing noteworthy as far as I can see..

I noticed nothing like that..

Right, the pink blocks are never affected by MVs, but also there is the
fact that there is never any MV in a frame where new pink blocks appear..

That leads me to think that it is something MV related that is making
these problems.

Also note that the pink blocks are transparent..  It kinda looks like an
color offset is applied..  I'm thinking memory management or bitstream
errors in conjunction with MV code..  Just my 0.02$
