Diagnosing NS_E_WMP_CONVERT_NO_RIGHTS_ERRORURL during Windows Media library import

NS_E_WMP_CONVERT_NO_RIGHTS_ERRORURL (0xC00D1159) is returned when conversion was denied by content rights and the provider supplied an error/help URL.

Identify whether library insertion reached path validation, type detection, plug-in activation, rights evaluation or database update. This result identifies a narrower stage than the dialog text exposes, so preserve its operation before trying a workaround. In this case the rejected checkpoint is conversion was denied by content rights and the provider supplied an error/help URL.

Library-import boundary

AllStat already supplies the standard user-facing description for this HRESULT; this custom block instead isolates the additional technical boundary. Earlier success in file lookup, network connection, parser creation or graph construction does not prove that the later the operation is valid.

Case-specific checkpoint: rights action requested, content header, provider URL, license state and whether simple playback is permitted. The controlled comparison for this HRESULT is: query playback and copy/import rights separately, then open the supplied URL without exposing license material.

Closest distinction: The NOERRORURL variant has the same rights boundary but no provider help endpoint.

Handler and source evidence

Capture	Why it matters for this HRESULT
Object or resource	rights action requested, content header, provider URL, license state and whether simple playback is permitted
State snapshot	Record the Player openState/playState or operation phase, object identity and exact timestamp when this result was returned.
First lower result	Keep the earliest Win32, Winsock, COM, parser, codec, DRM or device result that appears before this result.
Comparison record	Use one known-good case that follows the same API, protocol and component path while changing only the rejected precondition.

Controlled import comparison

Freeze the current object state and collect rights action requested, content header, provider URL, license state and whether simple playback is permitted.
Reproduce this result once without automatic retries or fallback applications.
Change only one precondition: query playback and copy/import rights separately, then open the supplied URL without exposing license material.
compare the first nested status and next Player event with the failed run.
After testing it, restore the original configuration if the change was diagnostic only.

Interpreting the library result

Retest outcome	Interpretation
Same it on the same object	The governing state or value is unchanged, or the caller is reusing an object created before the relevant change.
Fresh object succeeds	Lifetime, cached configuration or stale playlist/graph state contributed to it.
A later HRESULT appears	The rejected condition — conversion was denied by content rights and the provider supplied an error/help URL — was cleared for this HRESULT; diagnose the new code at its own layer.
Only one item or endpoint fails for this HRESULT	The evidence favors resource-specific data, rights, routing or device state rather than a global Player failure.

Actions that obscure the cause

assuming playback permission automatically grants library conversion.
Do not discard the first occurrence by repeatedly invoking Play, open, save or retry; later events can replace its original state.
do not publish credentials, private URLs, license material or complete protected-content headers; retain only redacted identifiers, lengths, hashes and protocol fields.

Technical references

After it, a different downstream HRESULT is progress and should be recorded as a separate condition.
