Encoded Video contains abnormality

Hi ppl,
I have encoded a whole dvd to divx/avi format using nero 6 enterprise, and upon playback of the finished encoded video it contains lines throughout one fifth of the screen and what seems to be almost like a mirror image of everything to the right of it. The actual picture quality is quite good but as you can already guess the lines are staring to annoy me a bit. What’s actually causing this problem and how do i rectify it???
