Try increasing the gamma value. If you use kuickshow as image viewer you
could press "g" four times to lighten the images up. Then you will see
that either libavcodec or xvid is faulty.
btw. you can use gimp to show the difference between both images. The
difference image won't be all black. Increase the gamma value to brighten
