Windows 10 Video Won’t Play Error 0xc00d36c4: Opening Files the Movies and TV App Rejects

You double-click a video from your phone, camera, or a download, and the Movies & TV app shows “Can’t play” with the code 0xc00d36c4. When a Windows 10 video won’t play error 0xc00d36c4 slot dewa appears, the file seems fine but refuses to open.

The code means the app does not support the file format or the codec used inside it. A video file is like a container, and the codec is the method used to compress the picture and sound within it.

Windows 10 handles common formats such as MP4 with H.264 video, but many cameras and phones use newer or less common codecs, such as HEVC.

Adding the right codec or using a more capable player usually solves it.

Why This Happens

The error appears for these reasons:

• The video uses a codec not installed in Windows, such as HEVC or certain audio formats.
• The file is incomplete, damaged, or was copied while still being written.
• The file extension does not match the actual format inside.
• The video is on a phone or drive connected by a slow or unstable link.

Recordings from iPhones and many newer Android phones often use HEVC to save space.

Start With These Basic Checks

Check the file first.

1. Copy the video to the desktop and try playing it from there.
2. Try a different video from the same device to see whether the problem affects all of them.
3. Right-click the file, choose Open with, and try Windows Media Player or Microsoft Photos.
4. Check that the file size is reasonable, not just a few kilobytes.
5. Copy the video again from the original device if it was transferred.

If other videos play but one does not, that file may be damaged.

Going a Step Further

Add codecs or use another player.

1. Open the Microsoft Store and search for “HEVC Video Extensions.” Microsoft offers it for a small fee; some PCs come with it preinstalled.
2. Install other extensions such as “Web Media Extensions” or “AV1 Video Extension” if your videos use those formats.
3. Install a reputable free player such as VLC from its official website, which includes its own codecs.
4. On your phone, set the camera to record in a “Most Compatible” or H.264 format for future videos.
5. Use a video converter to create an MP4 H.264 copy for sharing.

A Word of Caution

Avoid “codec packs” from unknown websites, as they often bundle adware and can break other media apps. Keep original video files until you confirm that converted copies play correctly.

Final Thoughts

Error 0xc00d36c4 means the app does not understand the video format. Test the file, add the right codec from the Microsoft Store, or use a player such as VLC.
