VFW_E_DVD_INVALID_DISC

Exact result and bit fields

VFW_E_DVD_INVALID_DISC has the unsigned HRESULT value 2147746449 (0x80040291) and the signed 32-bit representation -2147220847. AllStat describes it as “The specified path does not point to a valid DVD disc”. In the operation that produces this result, the path supplied to the DVD graph builder does not identify a valid DVD-Video volume.

The high bit is set, so this value is a failure HRESULT. Its facility field is 4 (FACILITY_ITF) and its low code is 657 (0x0291). These fields classify this result, but they do not identify which filter, thread, device, file or graph generation returned it.

Contract boundary

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.

The practical owner to locate for this HRESULT is the DVD Navigator, graph builder, decoder inventory and renderer topology. When handling this result, capture the native result before a wrapper replaces it with a generic exception, and keep the graph generation or object identity with the record.

Step-by-step diagnosis

  1. Capture it at the first native return, not only at the top-level playback failure.
  2. identify the exact graph stage described here: the path supplied to the DVD graph builder does not identify a valid DVD-Video volume.
  3. compare the live object state, topology and input with the documented interface preconditions.
  4. Before changing filters, drivers, registry data or media for this HRESULT, collect the code-specific evidence below.
  5. Test one evidence-backed the correction on the smallest reproducible graph.
  6. Verify that the corrected run no longer returns it and does not merely replace it with a nearby HRESULT.

Conditions that can produce it

Evidence worth preserving

Log the interface and method, filter CLSID and friendly name, process and thread, graph state, connected pin names, media-type summary, renderer or device identity where relevant, and the first preceding HRESULT. Record lengths and hashes instead of raw content when the incident includes disc identifiers, navigation state, parental settings and media paths.

Correction strategy

Retry and recovery

Retry rule for this HRESULT: Retry after a valid DVD volume is mounted or the path is corrected. A safe it retry must use a changed capability, state, object generation or input. While recovering from it, preserve cancellation and avoid replaying side effects when the original operation may have partially completed.

How it differs from nearby results

VFW_E_BAD_VIDEOCD concerns Video CD media or reads, while it concerns DVD-Video volume validity. Keep those cases separate in telemetry, UI messages and retry policy because their next actions are different.

Example incident

A user selects a folder containing only copied VOB files but no complete DVD navigation structure; validating the volume before building explains it. This example keeps the diagnosis at the specific the boundary instead of treating every DirectShow failure as a codec reinstall problem.

Implementation notes

Code that handles it should preserve the original HRESULT, the failed stage and an opaque correlation identifier. After it, do not infer success from partial graph construction, and do not continue using interfaces retained from a graph or device generation that has already changed.

Operational remediation for this HRESULT should favor supported component installation, device configuration and documented DirectShow calls. Manual registry or driver changes are appropriate only when the collected evidence for this HRESULT points to that layer and a rollback is available.
