Diagnosing NS_E_WMP_TAMPERED_CONTENT in the Windows Media Player playback path

NS_E_WMP_TAMPERED_CONTENT (0xC00D11C5) is returned when integrity or protected-content validation indicates that the media bytes or associated protection data have been altered.

Preserve the protected-content identity, integrity result, license state, and component that detected the mismatch. Re-downloading or replacing the asset may remove evidence needed to distinguish corruption from a trust-chain problem.

Controlled playback comparison

Freeze the current object state and collect file hash, acquisition source, DRM header, signature/integrity result, storage errors and known-good copy hash.
Reproduce this result once without automatic retries or fallback applications.
Change only one precondition: compare with a newly acquired byte-identical or provider-verified copy without editing metadata.
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.

Actions that obscure the cause

using a hex editor to remove protection headers.
