VFW_E_DVD_CHAPTER_DOES_NOT_EXIST
Meaning
Windows documents VFW_E_DVD_CHAPTER_DOES_NOT_EXIST as “The operation failed since the chapter does not exist”. Here, a chapter-specific DVD command names a chapter outside the current title’s authored chapter range.
Conditions that can produce it
- Cause 1: the chapter number is zero or above the title count.
- Cause 2: cached chapter data belongs to another title.
- Cause 3: the disc uses a different title layout than the application expected.
Relevant contract
This result belongs to the legacy DirectShow DVD Navigator contract. DVD state is authored and stateful: domains, user-operation controls, titles, menus, streams, command objects and graph construction each impose different preconditions.
Start with the DVD Navigator, graph builder, decoder inventory and renderer topology.
Evidence worth preserving
- Evidence 1: requested title and chapter.
- Evidence 2: GetNumberOfChapters result.
- Evidence 3: title-change events and UI selection source.
Correction strategy
- Action 1: validate chapter numbers against the current title.
- Action 2: refresh chapter lists on every title change.
- Action 3: handle titles with unusual or zero chapter counts.
Example incident
A saved shortcut points to chapter 12, but a replacement disc edition has only ten chapters; validating the current title prevents it.
Retry and recovery
Retry rule: Retry after choosing a valid chapter in the current title.
How it differs from nearby results
VFW_E_DVD_TITLE_UNKNOWN means no current title context exists, while it rejects a specific chapter in a known title.
