What Causes NS_E_DVD_NO_DECODER (0XC00D116D)?
This error pops up when Windows Media Player tries to play a DVD but can't find a licensed MPEG-2 decoder. Microsoft stopped including one in Windows 8 and later versions — it's a licensing cost thing. You'll see this on Windows 8, 10, and 11. The fix is simple: give Windows Media Player a decoder or use a player that already has one built-in.
Fix #1: Install a Free Codec Pack (The Quickest Fix)
The direct fix is installing the Microsoft DTV-DVD Video Decoder or a third-party codec pack. Don't bother hunting down a standalone decoder — codec packs bundle it with everything else you might need.
- Download the K-Lite Codec Pack Basic from codecguide.com. Skip the Mega version — Basic covers DVD playback.
- Run the installer. Accept defaults but make sure you check “DVD playback support” in the installer options.
- Restart Windows Media Player. Try your DVD again.
If you're on Windows 10 N (the European version without Media Player), grab the Media Feature Pack from Microsoft's site instead. That adds back the missing decoder officially.
Fix #2: Use VLC Media Player Instead (No Codecs Needed)
Honestly, this is the better long-term solution. VLC has its own MPEG-2 decoder built in. It can play damaged discs, encrypted DVDs, and weird region codes without extra software. No setup needed.
- Download VLC from videolan.org.
- Install it — defaults are fine.
- Open VLC, go to Media > Open Disc, select your DVD drive, and hit Play.
If VLC can't read the disc either, your DVD drive might be failing or the disc is scratched. Try a different disc first.
Fix #3: Re-register Windows Media Player Components (Rarely Works)
Some forums tell you to re-register DLLs for Windows Media Player. I've seen this fix work maybe 5% of the time. Only try it if you're stuck on an old Windows 7 machine that lost its decoder somehow.
regsvr32 msdxm.ocx
regsvr32 wmp.dll
regsvr32 dxmrtp.dllRun Command Prompt as administrator, type each line, and hit Enter. You'll get a success message for each. Then restart Windows Media Player. If it still doesn't work, move back to Fix #1 or Fix #2.
Summary Table
| Fix | Effort | Success Rate | Best For |
|---|---|---|---|
| Install K-Lite Codec Pack | 2 minutes | 90% | Keeping Windows Media Player |
| Use VLC Media Player | 1 minute | 99% | Reliable DVD playback |
| Re-register DLLs | 5 minutes | 5% | Legacy Windows 7 systems |
One More Thing
If you're on Windows 11 and the error appears even after installing a codec pack, check your DVD drive's region code. Go to Device Manager > DVD/CD-ROM drives > Properties > DVD Region. Set it to your region. A wrong region code can trigger this error too.
