What does HRESULT 0xC00D10BF (NS_E_PLAYLIST_CONTAINS_ERRORS) mean?

NS_E_PLAYLIST_CONTAINS_ERRORS

Diagnosing NS_E_PLAYLIST_CONTAINS_ERRORS in Player settings or the playback graph

NS_E_PLAYLIST_CONTAINS_ERRORS (0xC00D10BF) is returned when a playlist loaded as a container but at least one child item produced an error.

Separate Network-object configuration, graph capabilities, graphics presentation, stream selection and COM ownership before changing playback content. Record what the Player had already completed because later retries often replace the original evidence. The specific rejected condition is a playlist loaded as a container but at least one child item produced an error.

One-variable verification

1. Start from the original call and log 0xC00D10BF together with its object and operation phase.
2. Collect per-item HRESULTs, item URLs, index order, rollover choices and whether valid entries continue playing before changing the machine.
3. Use this single-variable test: build a new list from only the first failing item and reproduce its own HRESULT directly.
4. Repeat on a fresh object if the original predates a configuration, device or resource change.
5. Validate the expected next operation, not just initial open or object creation.
