abyss problems

I'm no expert but no beginner either.I;ve ripped abyss and re-encoded but when I have the finshd disc it has shadows,e'g' when someone walks it looks like another 5 of him walking as well slow motion almost. Any ideas people,any reply appreciated. To add if you have ripped this film let me know it can be done and that will let me know it is possible,i don't like giving up!

the abyss is a seamless branching dvd check the guide if you keep only the short version and one audio tracks and remove a part of the end credits, it fits on a dvdr, i've done it,no need to reencode +++

Many thanks Kheops,I will check out the link and find out more,what would you recommend for cutting the end credits.Thanks again for your help ,very much aprreciated.
