Looking at the Jackie Brown DVD, I can see what the problem is.
- Each menu is preceded by an intro clip of about 3-5 seconds. This intro clip actually has buttons, but they're all squashed at the top left corner! You can see that easily in PgcEdit:
MenuShrink is fooled into thinking it should preserve this menu, which it does, but the menu is not functional, of course. I'm not sure whether I'll improve MenuShrink to detect and skip such menus. In the meantime you can fix that easily in PgcEdit. If you double click on the PGC in question (the PGC for the menu that has the intro clip), you'll see this:
You can see the intro clip 1/1 followed by the real menu 1/2 (click on the arrow for a preview). Now double click on the 1/1 button, and change that to read 1/2. Do that for all the menu intro clips. This will essentially skip them, in this case, playing 1/2 instead.
Save your DVD and test before burning.
This will take care of it...
