Hall, I puzzled over this for awhile too, and accidentally solved my problem. Perhaps this is what you're referring to--
Under <create disk> <menu preferences>, to the right of "all templates" there's an icon. If I hold my mouse over it, it displays "reload menu." I left-click that icon and my "previously hidden" custom menus I created are now displayed. I didn't see this anywhere in the instruction manual.
Cheers......Lee
