NS_E_MPDB_GENERIC
What this HRESULT means
NS_E_MPDB_GENERIC is HRESULT 0xC00D0FCC. It means the media database operation failed without a narrower library HRESULT; the result belongs to the Windows Media Player library and media database, not to an unspecified Player failure.
The additional test for the mpdb generic condition is to record the database operation, profile, item identifiers and the first storage or access error beneath the library layer; that evidence is more useful than reinstalling the Player or changing several unrelated settings at once.
How to prove the condition
- Preserve
0xC00D0FCC, the ErrorItem context and the object instance involved in mpdb generic. - Compare the failing mpdb generic artifact with a known-good artifact that differs only in the suspected property.
- Separate acquisition, parsing, object construction, playback and persistence until the owner of mpdb generic is clear.
- Confirm mpdb generic directly: record the database operation, profile, item identifiers and the first storage or access error beneath the library layer.
- After you repair the specific database, access or object-state cause before reopening the library for mpdb generic, recreate the owning WMP object and verify that the corrected generation completes.
Minimum useful incident record
Capture the mpdb generic state before the Player advances, reloads, rescans or destroys the owning object:
- Artifact: media object ID or HME container/item ID for the mpdb generic reproduction.
- State: scan/search generation and the request that superseded it for the mpdb generic reproduction.
