NS_E_DRM_SOURCEID_NOT_SUPPORTED

Interpret the security decision

At 0xC00D280E, NS_E_DRM_SOURCEID_NOT_SUPPORTED records that the license/content source identifier requires a client feature not implemented by this DRM version. The subsystem producing this result is Windows Media DRM client internals, not the media decoder; it performs the client DRM engine that initializes security components, validates content and license identifiers, performs individualization, manages license chains and coordinates protected playback capabilities.

Start by capturing source ID, content header version and client DRM generation.

Values to compare

Field	Value
Policy input	requested action plus the exact license, certificate, profile, output or registration property evaluated by this result
Temporal state	trusted/system time, validity interval, request sequence and retry number when they influence this result
Direct check	capture source ID, content header version and client DRM generation

Do not lose object identity

It is meaningful only while the following state remains associated with one operation: DRM component version, KID, content header signature, license chain, uplink license, individualization state, portable-device registrations and local configuration. Preserve the KID and header hash, DRM component version, individualization status, license-chain identifiers, registry/configuration lookup and the first client callback reporting the failure.

The producing layer has not made a claim about every media operation; it has only established that the license/content source identifier requires a client feature not implemented by this DRM version.

How the operation should advance

A useful failure model links cause and recovery: the license/content source identifier requires a client feature not implemented by this DRM version. Verify that model when you capture source ID, content header version and client DRM generation, then make the smallest change needed to use a newer compatible client or obtain content issued for the supported DRM generation. Use a known-good counterpart only as a control; do not replace the failing artifact before its identifiers and hashes are recorded.

Keep the scope narrow

The license/content source identifier requires a client feature not implemented by this DRM version.

From HRESULT to cause

Preserve it and 0xC00D280E before cleanup, fallback or another media item changes the context.
Apply the targeted fix: use a newer compatible client or obtain content issued for the supported DRM generation.
Associate it with its current Windows Media DRM client internals object and the requested action.
Run the direct check: capture source ID, content header version and client DRM generation.
Compare the failure with a known-good case that changes only the property named by this condition: the license/content source identifier requires a client feature not implemented by this DRM version.

Distinguish from nearby results

Result	Why it points elsewhere
`NS_E_DRM_LICENSE_NOWDM`	the protected audio license requires WDM audio drivers, but the active path is not WDM-capable
`NS_E_DRM_LICENSE_NOTRUSTEDCODEC`	the codec selected for protected content does not meet the license trust requirement
`NS_E_DRM_NEEDS_UPGRADE_TEMPFILE`	a pending DRM component upgrade depends on a temporary upgrade artifact that cannot be used as expected

Fix and verify

Repair the owner of the check: use a newer compatible client or obtain content issued for the supported DRM generation.

Preserve the evidence before making changes.
