how to cut a video dvd


I would like to edit some video dvds., i.e. I would like to perform two different tasks:

take out a sequence from the middle of a video dvd and burn it to a new dvd

take out a sequence of each of two or more video dvds and burn a new dvd with each of the sequences building one of the chapters of the new dvd.

does anyone have hints on applications best suited for that purpose?
foolproof :shame: tutorials or step-by-step instructions would be highly appreciated.
