Use VLC Media Player or MediaInfo to check the runtime. A true duplicate will have the exact same duration (e.g., 2h 11m 23s). If durations differ, you have two different cuts (theatrical vs. extended).
Most users ignore duplicates, thinking, "I’ll just keep the larger one for better quality." This is a dangerous assumption. Here is what you are actually risking:
A: Conversion changes the container, not the content. You will still have duplicate content—just a different file extension. Use conversion only if your TV does not support MKV.
A: Playing the file is less risky than downloading new ones, but scan it first with Windows Defender or Malwarebytes. MKV files can contain embedded scripts in certain containers. Disable "automatic subtitle download" in your media player.
Contrary to promises of "1080p Blu-ray," many 123mkv rips are: duplicate movie 123mkv
Duplicate files may also contain spam links in their metadata.
If you’d like, I can expand this into a full one-page pitch, a treatment, character bios, or a trailer script.
