Trying to remove special edition version of movie and keep theatrical

I’ve been trying to remove the special edition version of a movie and just leave the theatrical version on the disc. If I’d keep both versions of the movie on the disc the bitrate would be extremely low and I wouldn’t be able to tolerate it. Can someone please recommend some software to me? I want to keep all menus BTW…

In DVD Shrink just replace the title you don’t want with a still image.
