as i understand the OP he doesnt want to rip the DVD but he wants to edit the chapters and cut scenes .

for this i think he needs a video card and a programm from pinaccle or something to do this?

if it is only ripping, there are plenty of easy to go ripping programs.

and it is not forbidden to rip a DVD if it is your own DVD as this one has not copyrights.

but it may be forbidden to have programs which delete the CSS protection of your DVD,
