Extract Audio and video from Multiplex karaoke DVD and re author

[quebecLA]

Sorry. I'm really not sure of terminology. I want to take audio from multiplex karaoke DVD, edit audio (which i know how to do) and burn another dvd with the video from original DVD and the edited audio.

(I will be changing the pitch of the audio).

I'm looking for software that will let me extract the audio and video from the DVD and later combine back into a playable dvd.

I don't mind if I have to pay for the software. I want something that makes the process as simple as possible.

I am very grateful for any help you can give me.
