What does HRESULT 0xC00D0FF3 (NS_E_WMP_CANT_PLAY_PROTECTED) mean?

NS_E_WMP_CANT_PLAY_PROTECTED: the failing boundary

NS_E_WMP_CANT_PLAY_PROTECTED (0xC00D0FF3) means The file cannot be added to the library because it is a protected DVR-MS file. This content cannot be played back by Windows Media Player. The important boundary is protected DVR-MS library policy; do not replace this result with a broader “Windows Media failed” diagnosis.

What this result proves

This code proves that the protected DVR-MS content cannot be added/played by this Windows Media Player path. It does not, by itself, prove a codec, permissions, network, device, or media problem outside that boundary. Preserve the first lower-level result when one exists, because later Player or Encoder errors can hide the original cause.

Evidence and focused verification

Record file type and protection state; do not troubleshoot codecs or network delivery when policy rejects the protected content itself. Keep the media object, endpoint, profile, or device identity fixed while changing only that rejected precondition. A successful retest should pass this exact boundary; a different HRESULT from a later stage is new evidence, not recurrence of NS_E_WMP_CANT_PLAY_PROTECTED.
