MF_E_DRM_HARDWARE_INCONSISTENT
MF_E_DRM_HARDWARE_INCONSISTENT belongs to the protected-content rights layer. It indicates that DRM state associated with the machine or its licenses is inconsistent; it is not a container parsing error and should not be diagnosed from video frame data.
Determine whether the problem follows the machine or one asset
- Test more than one known protected asset while keeping the same protected-playback implementation.
- Record whether rights acquisition, license restoration, or platform servicing occurred immediately before the first failure.
- Preserve the original HRESULT from the content-enabling path and any later PMP trust or policy errors separately.
A broad failure across protected assets points to DRM/platform state rather than a single media file. Avoid deleting license stores or copying DRM data from another system as an improvised repair; protected-media state is tied to trust and machine-specific mechanisms. The supported path is to use the content provider or platform recovery/renewal process and then recreate the PMP session so the protected path initializes from clean state.
