NS_E_DRM_UNABLE_TO_CREATE_PLAYLIST_BURN_OBJECT
What this HRESULT isolates
The symbolic result NS_E_DRM_UNABLE_TO_CREATE_PLAYLIST_BURN_OBJECT narrows 0xC00D276B to Windows Media DRM client API contract and object lifecycle. In practical terms, the DRM runtime cannot create the playlist-burn object required for this operation; the producing layer is the application-facing layer that initializes DRM support, validates parameters and properties, creates specialized objects, and delivers asynchronous status to the caller.
The built-in message summarizes the user-visible outcome, while the symbolic phrase “unable to create playlist burn object” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
Diagnostic inputs that separate the causes
Capture the first occurrence before retry or teardown changes state. The smallest useful record contains:
- Code-specific proof: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
- Protected identity: first inner HRESULT before an application replaces it with a generic error.
- Operation state: exact interface method and object type being created.
- Persistence or transport: SDK/runtime version and linked DRM stub library.
- Security context: property name, type, size and initialization order.
- Correlation point: operation state, callback sequence and cancellation owner.
Prefer IDs, hashes, sizes, and timestamps. Never log keys, passwords, licenses, or decrypted media.
How to prove the condition
- Start from
0xC00D276Band map it to the first WMDRM object that returned it. - Separate content/header evidence, license evidence, machine/device evidence and service/network evidence around “unable to create playlist burn object”.
- Before retrying this result, check whether another “unable to create playlist burn object” operation was active or whether the previous result may have committed partially.
- Apply the smallest supported fix: correct component/version or initialization state and create a fresh playlist-burn object; avoid resetting unrelated protected state.
What a supported fix should change
The supported response to this result is narrow: correct component/version or initialization state and create a fresh playlist-burn object. After correcting it, reopen or recreate the object that owned “unable to create playlist burn object” so cached state from the failed generation is not mistaken for the repair result.
Representative case: The application reaches the playlist-burn stage but object construction fails before any content or server work begins.
Do not merge these HRESULTs
| Result | Different boundary |
|---|---|
NS_E_DRM_UNABLE_TO_CREATE_PLAYLIST_OBJECT | The DRM runtime cannot create the playlist object required for this operation. |
NS_E_DRM_OPERATION_CANCELED | The active DRM operation was canceled before completion. |
NS_E_DRM_NOT_CONFIGURED | Required DRM properties have not all been supplied for the intended operation. |
Order the result event chain by timestamp; prefer the earliest specific result.
How to know the fix is real
A valid regression for it has two fixtures: one that deliberately produces “the DRM runtime cannot create the playlist-burn object required for this operation” and one that applies the targeted correction. Compare callback order, selected license/KID, final rights decision and persistence state; disappearance of the “unable to create playlist burn object” dialog alone is not proof.
What the missing object would have owned
In the path, the playlist-burn object normally enforces playlist and per-track burn limits before writing protected content. Object creation fails before that responsibility can be transferred to a live interface, so later player or server messages are secondary.
For this object specifically, preserve the playlist identity, track-burn counters and destination burner operation. A successful fix should create a new playlist-burn object and then complete its first real operation, not merely make the factory call return a different generic error.
