Interlace problems with moving objects using iDVD

Question

I had an MP4 file (created by a 3rd party) from a Hi-8 analog tape which has some interlace artifacts on moving images (left image of boy) but not too bad. When the MP4 files was imported into iMovie 11 the interlace artifacts smoothed somewhat - that was OK (right image of boy). The camera was still and the boy was moving.  Vertical lines on stationary objects are OK in all images. These are screen captures from the Mac of the mp4 played through quicktime and the same file imported into iMovie 11 and played.  I paused both to take the screen capture.
The completed project in iMovie 11 looked OK when previewed prior to rendering. These are 20 year old videos so my expections were being met.   I rendered the project with iDVD to the hard drive first and then to a DVD with the same poor imaging result on the moving object.  I am using a new Macbook Pro I bought in early January which came with iMovie 11 and iDVD  Ver 7.1.2 (1158). Running Mac OS X 10.7.3  Macbook Pro  2.3 Ghz Corei7   8GB 1333 Mhz DDR3.
I couldn't screen capture from the MAC DVD player screen to illustrate the poor result (got a checkerboard screen) so I took a photo of the screen and imported that (below).  The moving boy on the left is from an  iMovie 11 screen capture, the image on the right is the moving boy from the rendered DVD I paused on the Mac (and took a pic of).
Below a close up of the poorly rendered moving boy viewed on the resultant DVD.  This translates into a horrible rendition of any quick moving object.  It happens with any moving image - i.e. a pan across a room with straight vertical lines like edges of a wall will show as serrated and poorly rendered edge. I used a trial version of the Daniusoft DVD creator with the same result!  I am at a loss on how to resolve this issue.  Any thoughts out there??
I had previously used Pinnacle Studios on my old XP PC which worked great on other tape's Mpeg files and created great DVD's (never had an interlace problem) ... until my computer died .....  so I figured Apple and associated software should be at least equal if not a superior product.   Now I'm not too sure!
