add menues to dvd backup

I have purchased movies from other countries that have for example Shrek 1 and 2 on the same disc. When you put the dvd in, the menue is where you can click on 1 or 2 and start playing the movie. Any idea how I might can do this?

 

Are you asking whether and how you can put 2+ DVD to one disk preserving menus and adding disk selection menu?

Thanks alot. I believe this is the info I am looking for. Can this program (dvdremake) be more useful than dvd shrink and dvd decrypter?

 

More usefull? I dont think they are comparable. All these programs do different things. DVD Decrypter - rip/write; DVDShrink - transcoding; DvdReMake Pro - editing.
