Not that i know, there uses to be a known problem when MPEG
streams do end (MPEG code) w/o really ending (the end of file stream isn't
reached). Usually in this case, the encoding pipeline is
reset, resulting in a truncated 2pass log, often completly
corrupted as a close/create race could occur.
But this is not really xvid's fault, as it's caused by the
upper layer.
Can you post xvid4.cfg file, and the recipe to trigger the bug?
