NS_E_PDA_CANNOT_SYNC_INVALID_PLAYLIST
Failure boundary and ownership
NS_E_PDA_CANNOT_SYNC_INVALID_PLAYLIST with value 0xC00D1235 records expanding a malformed or stale playlist into synchronization items. The producing call and its state are more diagnostic than a later aggregate Player failure.
Underlying mechanism
At the checkpoint, automatic synchronization uses a Player-to-device partnership, a snapshot of selected playlists and a queue of per-item copy, delete or retrieval operations; The sync engine owns its own running state and can reject changes while a previous generation is active. The page-specific boundary is expanding a malformed or stale playlist into synchronization items.
A working manual file copy does not prove that the Player’s partnership, playlist snapshot and synchronization queue are valid. The condition can be reproduced when an old playlist contains invalid syntax or missing item references.
Trace fields worth keeping
| Evidence | Why it matters for cannot sync invalid playlist |
|---|---|
| Producing object and operation | device and partnership IDs, sync generation and state, selected playlist identity/version, queued item ID and direction, subscription account, target storage, progress callback and first item-specific HRESULT |
| Decisive observation | playlist identity/version, parser result, entries and unresolved media references |
| 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: repair or recreate the playlist and verify every entry before syncing. |
What the comparison proves
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with expanding a malformed or stale playlist into synchronization items; 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 sync invalid playlist 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 expanding a malformed or stale playlist into synchronization items.
Decision path
- Capture
0xC00D1235, it, the exact Player/API operation and the first timestamp at which it appears. - Save playlist identity/version, parser result, entries and unresolved media references; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- correlate the result with device and partnership IDs, sync generation and state, selected playlist identity/version, queued item ID and direction, subscription account, target storage, progress callback and first item-specific HRESULT.
- Reproduce once with the original source and destination, then apply only this change: repair or recreate the playlist and verify every entry before syncing.
- Create a fresh operation generation and verify that the original call advances beyond the cannot sync invalid playlist boundary.

NS_E_PDA_SYNC_FAILED | finalizing the synchronization generation after one or more queue operations failed |
Safe correction
Correct this boundary by making sure you repair or recreate the playlist and verify every entry before syncing. Then reacquire the interface or media state that produced it and repeat that call.
When verifying it, do not delete and recreate the partnership before exporting the selected playlists and recording the first failing item; otherwise the state needed to distinguish queue, account and device failures is lost.
