Pioneer PDV-10 Operating Instructions Manual page 13

DVDs are divided in units called titles, which are further divided in chapters. They
also include menu screens that do not belong to any title. With movies, normally
one movie corresponds to one title. On karaoke discs, one song corresponds to
one title. Some discs are not divided in this way, however, so be careful when
using the search and programming functions.

Disc operation
With some DVDs it is intentionally prohibited to change the operating method or
to perform certain operations. Because of this, operating procedures may differ
for different discs and for some discs certain operations may not be possible.
With Pioneer DVD players, a mark indicating the operation is prohibited
("prohibition mark") is displayed on the screen when the user attempts to
perform a prohibited operation. In addition, with discs on which interactive
operations are possible on menus or during playback, the data on the disc is
branched rather than continuous, so some operations (repeat, programming, etc.)
may not be possible. In such cases, Pioneer DVD players display a prohibition
mark.
