That sounds like an 'interleave' problem. Check to see if you have an option to make a 'progressive scan' or an 'interleaved scan' DVD in your DVD Workshop 2. If your original AVI(s) had interleaved scan then the DVD should be set to use it too. One caveat here, sometimes the AVI interleave is backwards and that makes the ghosting and vertical edge blur on motion much worse. The only fix is to reverse the interleave on the AVI. Virtual-dub, a free video tool, can do this.
