Using DVDSP 4.2.1, I am working on a project with a first play movie menu. There are two buttons on this menu, one invisible button (overlaying the title) connected to the main content (track 1), and one visible button connected to a second menu with contact info.
Here's the (strange) problem: in simulation mode, everything works as it should. The buttons react to the pointer as it passes over them, and activate correctly, sending the viewer to the right place. Once the burned DVD is played on either a set-top DVD player or Apple's own DVD player, the buttons will not activate UNTIL the menu's movie loops once. After the menu movie loops, the buttons become active. Even the enter button will not work until the movie loops.
I know this must be something simple, but I cannot figure it out...
