A system controller displays all setup items on a setup screen, at the
time of a setup mode in which a setup button 18a of a remote controller
is depressed, in case that it is judged that a disc is not loaded on a
tray of an apparatus itself, and, in case that it is judged that the disc
is loaded, then, judges a type of the disc which is loaded, and on the
basis of a result of that judgment, displays only a setup item which can
be used for the loaded disc, and does not display a setup item which can
not be used.
