originally, i wanted to demaux the vobsubs from the mkv files i had, so before i did anything, the subtitles would show perfectly in windows media player classic, then, i like installed mkvtoolnix so i can run mkvextractgui, and now the original mkv files dont show the subtitles anymore lol, im not sure what i did, i reinstalled vobsub and ffdshow as well. other files show subtitles but not these mkv files.
