Combine 2 DVDs into one

I have two versions of a DVD movie. One is widesceen format and one is full screen format. Unfortunately the widescreen version has Japanese menus. I'd like to combine the two into one DVD somehow so that I have the English menus and extra features from the fullscreen version but the video from the widescreen version. ADDED INFO I may not have thought this through enough. The DVD files will probably be too big to easily transfer back and forth via the internet. I'm thinking the easiest would be to just snail mail the disks to the winning bidder and have him or her snail mail the finished product back to me. Also, I'm not neccesarily looking for a whole new menu to be built. If the existing menu from the full screen version can be used then that would be fine. ## Deliverables 1) Complete and fully-functional working video in a format I can burn to a DVD 2) Deliverables must be in ready-to-run condition, as follows: Working English Menus, Widescreen video, No region code 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
