NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS
How to investigate NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS
The code 0xC00D1160 narrows the event to establishing a protected video output path accepted by the DVD playback graph. Treat NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS as a checkpoint in dvd navigator, decoder graph and protection policy and retain its first lower-level error.
What the Player is doing
At the NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS checkpoint, dVD playback is built around the DirectShow DVD Navigator, which parses DVD-Video navigation data and exposes separate video, audio and subpicture outputs; Decoder availability, title-domain state, region policy, parental level and copy-protection negotiation are independent checkpoints. The page-specific boundary is establishing a protected video output path accepted by the DVD playback graph.
For NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS, 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 realistic trigger is that the decoder graph builds but the selected video output cannot prove protection.
Capture before changing state
| Evidence | Why it matters for disc copy protect output ns |
|---|---|
| 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 |
| Decisive observation | display connection, renderer, decoder, graphics driver and copy-protection negotiation result |
| Generation identity | Record the same disc, device, job or Player operation generation that returned NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS; a reconnect or media change creates a different test. |
| Underlying result | Keep the first device, filesystem, COM, codec, DirectShow, IMAPI or BITS result seen before the Player mapped it to NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS. |
| Controlled comparison | Repeat the producing call after changing only this condition: use a supported protected output path and updated compatible display driver. |
Interpretation guide
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with establishing a protected video output path accepted by the DVD playback graph; correct that state before changing unrelated codecs, drivers or playlists. |
A lower layer failed before NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS | Preserve that earlier HRESULT or device result because NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS may be only the Player-level mapping. |
| The same call passes after one isolated change | The comparison supports the disc copy protect output ns diagnosis rather than a broad installation failure. |
The code changes after retesting NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS | The NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS boundary was passed; diagnose the new HRESULT as the next independent stage. |
NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS scopes the failure to establishing a protected video output path accepted by the DVD playback graph. The presence of NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS does not establish a system-wide media failure; verify its owning operation before changing unrelated Player components.
Five-step isolation test
- Capture
0xC00D1160,NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS, the exact Player/API operation and the first timestamp at which it appears. - Save display connection, renderer, decoder, graphics driver and copy-protection negotiation result; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- For
NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS, 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: use a supported protected output path and updated compatible display driver.
- Create a fresh operation generation and verify that the original call advances beyond the disc copy protect output ns boundary.
Different boundaries in the same family
| Related result | Different diagnostic boundary |
|---|---|
NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_FAILED | enforcing the disc’s analog/component-output resolution restriction |
NS_E_DVD_NO_SUBPICTURE_STREAM | connecting the DVD subpicture stream used for subtitles and menu highlights |
NS_E_DVD_COPY_PROTECT | completing DVD drive, navigator, decoder and renderer protection negotiation |
Correction criteria
The test is successful when you use a supported protected output path and updated compatible display driver, recreate the owning operation, and the original call no longer returns NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS.
When verifying NS_E_DVD_DISC_COPY_PROTECT_OUTPUT_NS, do not bypass region or copy-protection checks; Diagnose the supported playback path by preserving the exact disc, drive, decoder and display connection involved.
