Combining dvds with original functioning menus

[Reedo]

I have tried for weeks to combine 3 short homemade DVDs to one disc and keep the original menus functional.

Combining movies is a snap, and making new menus is a piece of cake- but I want to keep all 3 original menus functional.

I have tried several authoring programs, like DVDShrink, DVD-Lab etc.
TMPEG DVDAuthor came the closest, as I was able to create a main menu that points to each of the 3 discs (which have all the chapter stops etc) but I have to make all new menus. The other programs just combine all the movies together, and I really have to make a new menu then.

Has anybody accomplished this task? I have asked around a bit and several people have offered suggestions, but so far no one has told me how they did it.

I realize most likely this cannot be done, as I understand DVD file structures etc. I just have to believe someone out there figured out how to do this.

Thanx in advance..rw

I guess you should use the "old" menu's (also motion menu's?) as background(s) and make new menu links/chapter points in a program like
DVDLab, in DVDLab you can import the menu .VOB's
