DVDs
All discs are divided into smaller, more manageable sections so that you can find specific content

More specifically, discs are divided into one or more titles. Each title may be further divided into
several chapters. Occasionally, a chapter may contain index points, effectively dividing the chap-
ter into several parts as well.
