NS_E_DVD_REQUIRED_PROPERTY_NOT_SET
Where this result occurs in the Player workflow
NS_E_DVD_REQUIRED_PROPERTY_NOT_SET (0xC00D1173) marks validating required DVD playback properties before graph control begins. Keep this HRESULT attached to the producing operation even when the Player shows a broader message.
Mechanism
Successful reading of files from the DVD volume does not prove that the navigation program, decoder graph or protected output path can be used. A representative way to reach this result is that the graph is created but a required disc path or renderer property remains unset.
State snapshot
| Evidence | Why it matters for required property not set |
|---|---|
| Producing object and operation | disc path and media generation, DVD domain, title/chapter, region values for disc/drive/decoder, selected audio/video/subpicture streams, decoder CLSIDs, renderer and display mode, protection negotiation result and first DirectShow HRESULT |
| Key observation | required property names/values, object instance and method called |
| Controlled comparison | Repeat the producing call after changing only this condition: set every documented property before invoking the dependent operation. |
Controlled diagnostic sequence
- Capture
0xC00D1173, the exact Player/API operation and the first timestamp at which it appears. - Save required property names/values, object instance and method called; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- Correlate the result with disc path and media generation, DVD domain, title/chapter, region values for disc/drive/decoder, selected audio/video/subpicture streams, decoder CLSIDs, renderer and display mode, protection negotiation result and first DirectShow HRESULT.
- Reproduce once with the original source and destination, then apply only this change: set every documented property before invoking the dependent operation.

Focused correction
For this occurrence, set every documented property before invoking the dependent operation. Recreate only the object that produced it and repeat the original operation against the same controlled input.
During verification, do not bypass region or copy-protection checks; diagnose the supported playback path by preserving the exact disc, drive, decoder and display connection involved.
