NS_E_DVD_CANNOT_COPY_PROTECTED
Where this result occurs in the Player workflow
NS_E_DVD_CANNOT_COPY_PROTECTED (0xC00D1172) marks rejecting extraction or copying of copy-protected DVD content. 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 an application routes protected DVD sectors into a rip workflow.
State snapshot
| Evidence | Why it matters for cannot copy protected |
|---|---|
| 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 | disc protection state, requested copy/rip operation and navigator policy result |
| Controlled comparison | Repeat the producing call after changing only this condition: do not attempt the prohibited copy; use the disc through an authorized playback path. |
Controlled diagnostic sequence
- Capture
0xC00D1172, the exact Player/API operation and the first timestamp at which it appears. - Save disc protection state, requested copy/rip operation and navigator policy result; 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: do not attempt the prohibited copy; use the disc through an authorized playback path.

Focused correction
For this occurrence, do not attempt the prohibited copy; use the disc through an authorized playback path. 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.
Discriminating evidence: Record whether the requested operation would copy protected DVD content and capture the navigator's copy-protection state before retrying. This is a policy/protection refusal; it is distinct from region mismatch, parental restriction, malformed DVD navigation data, or output-protection negotiation failure.
