Is there a way to split a movie into two (to avoid any compression), but keep all the original menus on both? In other words, I'd like both resulting DVDs to be "self-contained," but with the first DVD having the first half of the movie, and the second having the second half.

Just process the DVD twice.
Each time after "Disabling" the unwanted titles and keeping the entire menu.

The disabled titles will be replaced by a blank color screen on each disk but the interactuvity of the menu is untouched.

To my knowledge this feature is inexistant in DVDshrink where you can but compress unwanted titles to still images.

I understand this: what I want to do is actually split the *movie* into two parts, so that the first half of the movie is one disk and the second half is on the second. All titles and menus on both disks ...
