File Structure Of Discs
DVD VIDEO
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.

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. (A pg. 29)
When you record a programme on a DVD-R/RW (Video mode) disc
