File Structure Of Discs	Navigation
	Files are automatically grouped as follows and displayed on the
DVD VIDEO	MP3/JPEG Navigation screen. Data is displayed in the
	alphabetical order of file name. Files are grouped based on roots.
Typically, DVD VIDEO discs are made up of larger units called
AtitlesB. Each title has a number (title number) that can be used to
select desired titles. Titles are further divided into units called
AchaptersB. Each chapter has a number (chapter number) that can
also be used to select desired chapters. Note that some discs are
not divided into titles and chapters.

When you record a program on a DVD-RAM/R/RW (VR mode) disc

A single recording session results in a single title (a single chapter). However, chapter marks are automatically inserted when recording is paused, or audio changes from monaural to stereo due to commercial breaks, etc. It is also possible to insert chapter marks at desired locations during playback.
