I should explain further what I want to do
3 old fashioned video tapes were copied onto DVD for me in VOB format.
I want to join the 3 together in order and edit the bad bits out and make one DVD that I can give to the grandparents. Each DVD has several files on it and I am not sure which files I actually need to copy onto my PC to edit.
Please also see my post below which says what happens with the application suggested by firecracker.
