Diagnosing `NS_E_WMPCORE_PLAYLIST_IMPORT_FAILED_NO_ITEMS`

0xC00D10B1 maps to this result. Its actionable interpretation is library import produced no items from the selected playlist within the Windows Media playlist and metafile state machine; the producing mechanism is the layer that turns ASX/WAX/WVX/WMX or library playlists into Media objects, resolves REF and ENTRYREF URLs, expands nesting, handles EVENT and REPEAT blocks and advances to alternates.

Evidence that separates the result

Field	What to record
What to verify	Record source playlist format, parsed item count and reasons items were excluded
Artifact identity	Resolved base URL for REF or ENTRYREF targets for the playback core playlist import failed no items reproduction
Runtime state	Current item index, alternate index and nested-playlist depth for this reproduction
Owning object	Repeat/event point and the media object expected at its start or end for this reproduction
Lower-level result	Playlist URL, format, response content type and exact downloaded bytes for this reproduction
Correlation	ASX version and element stack at the failure for this reproduction

Representative case: An empty or entirely filtered playlist is submitted to PlaylistCollection import.

Focused test and correction

Perform the code-specific test: record source playlist format, parsed item count and reasons items were excluded.
Make the targeted change—import a playlist containing resolvable media items—and repeat the same producing operation.
