Use a versatile player like VLC Media Player or MPC-HC , which handle MKV containers and AAC audio natively.

If the file contains multiple languages, you can switch between them in your player's "Audio" menu.

This is standard definition, suitable for viewing on smaller screens or mobile devices without consuming high bandwidth.

If subtitles are included, they are often "soft" (selectable) rather than burned into the video, allowing you to toggle them on or off.

This indicates the video was captured from a Netflix stream (NF) and encoded into a smaller file size (HDRip).

The Matroska Video (MKV) container is used, which can bundle multiple audio and subtitle tracks into one file.
