VLC Not Showing Correct Title Of Movie

If the Name of the file is correct and the tag information is correct then you will probably find that the title is incorrect.

To check open the movie in VLC click on Tools, Media Information, under General if the name of the title is different  you will need to change it in a program called MKVmerge GUI.

Download from : https://www.bunkus.org/videotools/mkvtoolnix/downloads.html

Install then run mmg.exe from the mkvtoolnix folder.

Drag the MKV into the input files area, then swap to the Global tab.

It is here you rename the File/segment title to the correct name

Once renamed, click the button at the bottom named Start Muxing.

The MKV file will be renamed in the same directory as the source.
