How to Fix Error 0xc1010103 on Windows 10/11?

When you attempt to play an MKV video or an MP4 movie in the Movies & TV app or Windows Media Player, you may encounter a playback error like the one below:

Can't play.
Choose something else to play. This item is in a format we don't support.
0xc1010103

If your video plays fine in other media players, this error may be due to an unsupported codec format. Although MKV and MP4 are officially supported by Windows, if the video is encoded with an unsupported codec, it cannot be played through the Windows media player apps.

As you probably know, a codec is a piece of software used to encode and decode media files such as video and audio. A media player must have an appropriate codec to decode and play video encoded with that codec. Therefore, you can fix the problem by installing the missing codec or changing the codec to a Windows-compatible format.

Nevertheless, the 0xc1010103 error may be related to other issues, such as issues with your GPU drivers. Your GPU driver might be corrupted or outdated, but you can fix this by updating the GPU driver to the latest version.

It could also be due to broken system files or file corruption that lead to this video error.

Don't worry. Below, you will learn 7 methods on how to fix the 0xc1010103 error on Windows. Read on.

Your MKV or MP4 video is likely encoded with HEVC codec, a high-efficiency codec for encoding high-resolution videos such as 4K and 8K. But Windows does not have native support for HEVC, so you’ll need to manually download the missing codec.

Fortunately, you can install HEVC codec extensions directly from the Microsoft Store: HEVC Video Extensions ($0.99). After that, you can check if the media player plays your media file without the 0xc1010103 error.

However, if installing the HEVC codec doesn’t help or your video file plays without sound, it could be other wrong codecs. You can try downloading the K-Lite Codec Pack (free) that contains all the essential codecs for common video playback and see if it works. Or you can use a free video converter to convert the video to a Windows-supported format for a quick fix. See more details in the next method.
