One reason VLC may struggle with MKV files is due to codec issues. MKV files can contain multiple video, audio, and subtitle tracks in a single file.

Another possible cause is MKV file corruption, often due to incomplete downloads or power failures. Corrupted MKV files may freeze, stutter, or fail to open in VLC.

Using an outdated VLC version may also lead to difficulties playing MKV files efficiently. Updating VLC regularly can help resolve these playback issues and improve compatibility with various formats.
