NS_E_WMP_CANNOT_BURN_NON_LOCAL_FILE
Failure boundary and ownership
NS_E_WMP_CANNOT_BURN_NON_LOCAL_FILE with value 0xC00D10D6 records staging a burn item whose source is not a stable local file. The producing call and its state are more diagnostic than a later aggregate Player failure.
Underlying mechanism
At the checkpoint, windows Media Player builds a burn playlist, refreshes its calculated status and delegates physical recording or erase work to the optical-disc stack; The recorder, inserted medium, burn format, staging files and write engine each have a separate lifecycle. The page-specific boundary is staging a burn item whose source is not a stable local file.
A recorder that enumerates can still be busy, incompatible with the inserted medium or unable to sustain the selected write operation. The condition can be reproduced when the playlist contains an HTTP stream that has never been materialized on disk.
Trace fields worth keeping
| Evidence | Why it matters for cannot burn non local file |
|---|---|
| Producing object and operation | recorder unique ID and exclusive-access owner, inserted media profile/state, burn format, playlist item, source locality, duration/byte estimate, staging directory free space, write speed, current IMAPI action and underlying HRESULT |
| Decisive observation | item URL/path, scheme, cache state and whether a complete local copy exists |
| Generation identity | Record the same disc, device, job or Player operation generation that returned this result; a reconnect or media change creates a different test. |
| Underlying result | Keep the first device, filesystem, COM, codec, DirectShow, IMAPI or BITS result seen before the Player mapped it to this result. |
| Controlled comparison | Repeat the producing call after changing only this condition: download or copy the item to a verified local file before refreshing the burn playlist. |
What the comparison proves
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with staging a burn item whose source is not a stable local file; correct that state before changing unrelated codecs, drivers or playlists. |
| A lower layer failed before this result | Preserve that earlier HRESULT or device result because this result may be only the Player-level mapping. |
| The same call passes after one isolated change | The comparison supports the cannot burn non local file diagnosis rather than a broad installation failure. |
| The code changes after retesting it | The boundary was passed; diagnose the new HRESULT as the next independent stage. |
It scopes the failure to staging a burn item whose source is not a stable local file.
Decision path
- Capture
0xC00D10D6, it, the exact Player/API operation and the first timestamp at which it appears. - Save item URL/path, scheme, cache state and whether a complete local copy exists; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- correlate the result with recorder unique ID and exclusive-access owner, inserted media profile/state, burn format, playlist item, source locality, duration/byte estimate, staging directory free space, write speed, current IMAPI action and underlying HRESULT.
- Reproduce once with the original source and destination, then apply only this change: download or copy the item to a verified local file before refreshing the burn playlist.
- Create a fresh operation generation and verify that the original call advances beyond the cannot burn non local file boundary.

Safe correction
Correct this boundary by making sure you download or copy the item to a verified local file before refreshing the burn playlist. Then reacquire the interface or media state that produced it and repeat that call.
When verifying it, do not repeatedly start a new burn against a drive that still owns or finalizes the previous session; Capture the media state and recorder owner before ejecting or replacing the disc.
