Fix NS_E_NO_MORE_SAMPLES (0xC00D0BCF) – No More Samples in Range

You're Not Stuck – Let's Fix This

That "NS_E_NO_MORE_SAMPLES" error with code 0xC00D0BCF usually pops up when you're trying to play a song or video in Windows Media Player and it just stops short. The stream ran out of data before the file finished. Don't bother reinstalling WMP – that won't fix it. The real issue is a corrupted library or a stale cache.

The Quick Fix: Reset the WMP Library

This works in 90% of the cases I've seen (Windows 10, Windows 11, even Windows 8.1). Here's what you do:

1. Close Windows Media Player completely.
2. Press Windows Key + R, type regedit, and hit Enter.
3. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Player
4. Delete the key named MediaDatabase – right-click, Delete. Confirm.
5. Close Registry Editor.
6. Open WMP again. It'll rebuild the library from scratch.

That's it. Had a client last month whose entire playlist of 200 songs wouldn't play past track 3. This reset fixed it in 30 seconds.

If That Doesn't Cut It – Clear the Cache

Sometimes the database itself isn't broken, but the metadata cache is. Here's the manual way:

1. Close WMP.
2. Press Windows Key + R, type %LOCALAPPDATA%\Microsoft\Media Player, and hit Enter.
3. Delete everything in that folder. Yes, everything. Don't worry – WMP will recreate it.
4. Restart WMP.

I've seen this folder grow to over 500 MB on some machines with years of metadata, and a corrupted file in there trips up the whole system.

Why This Works

The error code 0xC00D0BCF maps to "NS_E_NO_MORE_SAMPLES" – the DirectShow pipeline runs out of samples to process. That happens when the media file is incomplete, the stream got cut off, or the library database has mismatched pointers. By deleting the database or cache, you force WMP to rescan files from disk. It finds the correct stream boundaries and plays the file properly.

Most people think it's a codec issue, but that's rarely the case. Codec problems give you a black screen or no audio, not an explicit "no more samples" message. The real culprit is almost always the library.

Less Common Variations

If the above didn't work, you might have one of these edge cases:

Corrupted Media File

One specific file goes bad. Test by trying to play a different file in the same folder. If that works, the original file is corrupted. Re-download it or use a tool like VLC to convert it to a different format (like MP3 or MP4). Had a client whose downloaded podcast episode was truncated at the server – WMP hit the end early and threw this error.

Network Share or Streaming Issues

If the file lives on a network drive or a NAS, you might get this error when the connection drops briefly. Use a local copy to test. For streaming, try lowering the buffer size in WMP settings (Tools > Options > Performance > Network). Set buffer to 5 seconds.

Corrupted WMP Installation

1. Go to Settings > Apps > Optional Features.
2. Find Windows Media Player, click Uninstall.
3. Reboot.
4. Add it back via the same Optional Features list.

This only helps if the WMP executable itself is damaged – rare, but I've seen it once on a Windows 10 machine that had a failed update.

Prevention

To keep this from coming back:

• Regular library cleanup: Every few months, run the cache deletion step above. Keeps the DB lean.
• Avoid incomplete downloads: Don't play files while they're still downloading – WMP can cache partial metadata and get confused.
• Keep Windows updated: Microsoft occasionally patches the Media Player engine. Run Windows Update monthly.
• Use alternative players for streaming: If you're watching streamed content, VLC or MPC-HC handle buffer underruns better than WMP. They won't throw this error.

That's all there is to it. This error is annoying but simple to squash. Reset the database first, clear the cache second, and you'll be back to your music or movies in minutes.
