I have a simple project with one time line and chapters. I have a main menu with buttons linking to 4 sub-menus. Each sub-menu (except the last) has five buttons linking to chapter markers and one button linking back to the main menu. The last menu has only four chapter buttons and a return button.
For reasons I can't discover, the return to main menu button only works on the last sub-menu when the DVD plays on both of my DVD players. However, every return button works in the Encore preview, and works when the DVD is played on a computer.
All the settings appear to be the same, but the action isn't.
