NS_E_UNCOMPRESSED_DIGITAL_VIDEO_PROTECTION_LEVEL_UNSUPPORTED
Read the code before the dialog
The producer of 0xC00D2906 has determined that the uncompressed video rendering path cannot enforce the license’s minimum protection. NS_E_UNCOMPRESSED_DIGITAL_VIDEO_PROTECTION_LEVEL_UNSUPPORTED runs inside Windows Media DRM output protection, where the implementation handles license-policy evaluation that compares the content owner’s required output protection level or scheme with the active audio/video output path.
Confirm the producer by doing one thing first: capture renderer, connector and uncompressed-video OPL negotiation.
Correlate the owner and the policy
A complete incident ties together license OPL fields, play or copy action, output connector type, compressed/uncompressed state, driver-reported protection capability and selected rendering path; the minimum correlation set is the requested action, required OPL values, active connector, negotiated protection mechanism and whether the stream is compressed at that boundary.
A later generic error must not replace this evidence: the original condition remains that the uncompressed video rendering path cannot enforce the license’s minimum protection.
The final dialog can be broader
The uncompressed video rendering path cannot enforce the license’s minimum protection.
Why the first HRESULT matters
When documenting this result, state the rejected input and the expected successor state. The rejected input is demonstrated when you capture renderer, connector and uncompressed-video OPL negotiation; the successor becomes reachable after you choose a protected display path and compatible signed driver.
Minimum evidence set
| Field | Value |
|---|---|
| Direct check | capture renderer, connector and uncompressed-video OPL negotiation |
A controlled reproduction
- Preserve it and
0xC00D2906before cleanup, fallback or another media item changes the context. - Compare the failure with a known-good case that changes only the property named by this condition: the uncompressed video rendering path cannot enforce the license’s minimum protection.
- Apply the targeted fix: choose a protected display path and compatible signed driver.
- Associate it with its current Windows Media DRM output protection object and the requested action.
- Run the direct check: capture renderer, connector and uncompressed-video OPL negotiation.
Contrast with related results
| Result | Why it points elsewhere |
|---|---|
NS_E_OUTPUT_PROTECTION_LEVEL_UNSUPPORTED | the active output path cannot meet the license’s overall minimum protection level |
NS_E_COMPRESSED_DIGITAL_VIDEO_PROTECTION_LEVEL_UNSUPPORTED | compressed digital video leaves through a path below the required protection level |
NS_E_ANALOG_VIDEO_PROTECTION_LEVEL_UNSUPPORTED | the analog video output cannot apply the policy required by the license |
Recovery at the right layer
A matching correction is to choose a protected display path and compatible signed driver.
- Do not treat every output-protection result as a missing codec; the decoder can be present while the connector or driver cannot enforce the license policy.
