Is there anyway to process the main movie(s) and still allow to keep the menus, only without the "unnesessaries". I'm thinking in the same fashion as DVDShrink, which allows you to simply replace any content you don't want with a still image. This feature is useful for tv shows, using the menu only for navigation to specific episodes. I've used the "JOIN" funtion, which only seems to merge the episodes into a single duration, without chapters. Thank you forum.
The best program I have found for re-authoring and keeping a functional menu is CloneDVD from http://www.slysoft.com You can edit out what you do not want but preserve your menu. You can also do this if you split TV series disks and preserve the menu on both disks. You can try this program along with AnyDVD for 21 days.
Wish I could help more, Macs are foriegn to me. You might try the Mac forum maybe they have some answers. http://forums.afterdawn.com/forum_view.cfm/56
