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.
Configuration or graph boundary
AllStat already supplies the standard user-facing description for it; this custom block instead isolates the additional technical boundary. Earlier success in file lookup, network connection, parser creation or graph construction does not prove that the later the operation is valid.
Case-specific checkpoint: per-item HRESULTs, item URLs, index order, rollover choices and whether valid entries continue playing. The controlled comparison for it is: build a new list from only the first failing item and reproduce its own HRESULT directly.
Closest distinction: NS_E_WMP_MULTIPLE_ERROR_IN_PLAYLIST summarizes several queued failures; this code can also accompany a partially usable list.
State to capture before changing settings
| Capture | Why it matters for it |
|---|---|
| Object or resource | per-item HRESULTs, item URLs, index order, rollover choices and whether valid entries continue playing |
| State snapshot | Record the Player openState/playState or operation phase, object identity and exact timestamp when this result was returned. |
| First lower result | Keep the earliest Win32, Winsock, COM, parser, codec, DRM or device result that appears before this result. |
| Comparison record | Use one known-good case that follows the same API, protocol and component path while changing only the rejected precondition. |
One-variable verification
- Start from the original call and log
0xC00D10BFtogether with its object and operation phase. - Collect per-item HRESULTs, item URLs, index order, rollover choices and whether valid entries continue playing before changing the machine.
- Use this single-variable test: build a new list from only the first failing item and reproduce its own HRESULT directly.
- repeat on a fresh object if the original predates a configuration, device or resource change.
- validate the expected next operation, not just initial open or object creation.
Reading the next state
| Retest outcome | Interpretation |
|---|---|
| Same this result on the same object | The governing state or value is unchanged, or the caller is reusing an object created before the relevant change. |
| Fresh object succeeds | Lifetime, cached configuration or stale playlist/graph state contributed to this result. |
| A later HRESULT appears | The rejected condition — a playlist loaded as a container but at least one child item produced an error — was cleared for it; diagnose the new code at its own layer. |
| Only one item or endpoint fails for it | The evidence favors resource-specific data, rights, routing or device state rather than a global Player failure. |
Actions that obscure the cause
- treating the aggregate HRESULT as the root cause for every item.
- Do not discard the first occurrence by repeatedly invoking Play, open, save or retry; later events can replace its original state.
- do not publish credentials, private URLs, license material or complete protected-content headers; retain only redacted identifiers, lengths, hashes and protocol fields.

Retain before-and-after evidence for it so object recreation or content replacement is not mistaken for random retry success.
