How to extract scenes from a dvd???

Hello, I have a question that prob. has been addressed before...


I have a situation where I have a movie that I want to cut certain scenes from it... Both the video and audio (dobly digital/DTS).. without changing the quality of the orig. footage...

What program will do this for me.... I have spent many, many hours searching for a program that will do this... (expecially that supports Dolby digital sound)..

Thanx for you time and help...
