I am using MP 2.3.2 64bit on Win10. For OTA TV here in the US, I can not figure out how to enable Closed Captioning/Subtitles. The documentation talks about a separate file needed, but on live or recorded TV, that data is included with the signal so I don't think that applies. When I go to the submenu that displays the option for Subtitles, it doesn't appear to do anything or even indicate it was selected.
