Please Help!!!

I was on making a back up of my Scary Movie 2 & i Was wondering if it is possible to remove the Trailers at the begining of the dvd (i know how to remove copyright logo's using ifo edit) and i thought it would just be the same to remove the trailers..

i've tried to just delete the vob which has these two movie traliers on but then dvd2one or dvd shrink does not process the film 'Vob missing'

If any one knows how to do this i would really like to know how

PLEASE HELP ME!!!!!
