Fix Item Unplayable 0xc00d36e5 Error

This error appears when Windows Media Player or other media apps can’t play a video or audio file, often due to missing codecs, corrupted files, or DRM issues. This guide walks you through practical fixes to get your media playing again.

What You’ll Need

• Administrator access to your Windows PC (for some steps)
• The problematic media file (to test fixes)
• Optional: a USB drive or external storage to back up files

Step-by-Step

1. Restart your computer and the app. Close the media player completely, restart your PC, then try playing the file again. This clears temporary glitches that sometimes trigger the error.
2. Check if the file is corrupted. Try playing a different file in the same app. If other files work, the problem is likely the file itself. If all files fail, the issue is with the app or system codecs.
3. Run the Windows Media Player Troubleshooter. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters, select Windows Media Player, and run it. Follow the prompts to apply any fixes.
4. Install the latest codec pack (if needed). Many media files use codecs like H.265 or VP9 that Windows may lack. Download a reputable codec pack like K-Lite Codec Pack from its official site, install it, and restart your PC. This adds support for a wide range of formats.
5. Re-register Windows Media Player. Open Command Prompt as administrator (right-click Start > Command Prompt (Admin) or Windows PowerShell (Admin)), type regsvr32 wmp.dll and press Enter, then restart your PC. This fixes registry issues that can cause the error.
6. Check for DRM issues. If the file is from a streaming service or has digital rights management (DRM), the error may be due to expired or missing licenses. Try playing the file in a different app like VLC Media Player (which ignores DRM) to see if it works. If it does, the DRM license is the problem—try re-downloading the file or updating the service app.
7. Convert the file to a compatible format. If the file is in an uncommon format, convert it using a free tool like HandBrake. Open HandBrake, select the file, choose a common preset like Fast 1080p30, and convert to MP4. Then play the converted file.
8. Update your graphics drivers. Outdated drivers can cause video playback errors. Go to your GPU manufacturer’s website (NVIDIA, AMD, Intel) and download the latest driver for your model, or use Windows Update to check for driver updates.
9. Reset Windows Media Player. Go to Settings > Apps > Apps & features, find Windows Media Player, click Advanced options, then Reset. This clears any corrupted settings.
10. Use a different media player. If all else fails, install VLC Media Player or MPC-HC. These players include built-in codecs and often play files that Windows Media Player cannot.

Common Mistakes

• Skipping the restart step. Many fixes require a reboot to take effect. Don’t skip it.
• Downloading codecs from untrusted sites. Always use official sources to avoid malware.
• Assuming the file is fine. If you downloaded the file, it might be incomplete. Re-download it.
• Not testing with another player. This is a quick way to isolate whether the issue is the file or the player.
• Editing the registry without backup. If you manually edit the registry, back it up first. The steps above don’t require manual registry edits, but if you try other advice, be careful.

Tips

• Keep Windows updated. Microsoft regularly adds codec support and fixes through updates.
• Use VLC for problem files. It plays almost anything without extra codecs.
• Check file extensions. Renaming a file’s extension doesn’t change its format; use a tool like MediaInfo to see the actual codec.
• Store media on local drives. Network drives can cause playback errors due to latency.

Troubleshooting

If the error persists after trying all steps:

• Check the file’s integrity. Use a tool like ffmpeg (command line) to check for errors: ffmpeg -v error -i file.mp4 -f null -. If it reports errors, the file is corrupted and needs re-downloading.
• Try playing on another device. If it works on your phone, the issue is your PC. If it fails on all devices, the file is likely corrupted.
• Run System File Checker. Open Command Prompt as admin and run sfc /scannow. This repairs corrupted system files that might affect playback.
• Check for conflicting codecs. If you have multiple codec packs installed, uninstall all of them and install just one.
• Disable hardware acceleration. In Windows Media Player, go to Tools > Options > Performance and uncheck Use hardware acceleration. This can resolve GPU-related issues.
• Create a new user account. Sometimes user profile corruption causes errors. Create a new admin account and try playing the file there.
