Error code 0xc1010103 primarily manifests when trying to play videos using the default Windows Media Player on Windows 10 and Windows 11 computers, specifically for MKV and MP4 files.

Codecs are essential software components that enable media players to interpret and process the audio and video data contained within a file.

Potential Causes of the Error Code 0xc1010103

Missing or Corrupted Codecs: Codecs are essential software components that enable media players to decode and play various video formats. If the required codecs are missing or corrupted, the media player will be unable to process the video file, resulting in the 0xc1010103 error.

Outdated or Corrupted Graphic Drivers: Graphic drivers are responsible for rendering video content on your screen. Outdated or corrupted graphic drivers can lead to various video playback issues, including error code 0xc1010103.
