Actually...none of the text shows up. This includes the non-linked text. Looks fine during preview, but the only thing that shows up on the finished disc is the highlighted link. Please tell me this is a simple fix that I am just overlooking!
Just select the text(s) and right click and select option "Bring to Front".
This also happen if you have a motion menu background video and text on the menu.
I'm having similar problem -- text doesn't appear on text-only buttons in prepared DVD. Works fine in Preview.
My first attempt was to copy a working button from one menu onto the menus where the buttons are appearing transparent. This didn't help. Seems to be a function of the menu, not the buttons.
I do have a motion background (though its just a single frame MPEG). By recreating the buttons I believe I have done the suggested Bring To Front.
