if I remember correctly, usually an error like this happens when in the 
second pass you reach a frame after the last one
encoded in the 1st pass (which very likely crashed).
The frame may be corrupt/incomplete; with mplayer try to seek in the 
original just before the last frame encoded
(divx2pass.log will tell you the number) and checks if it crashes, please.
