Sub titles

[Soulcharger]

I've been using MakeMKV for about a month and it works perfectly However I now can't seem to get sub titles to appear! They always used to appear but not now! When I look at the online help there's a picture of how to do that but don't have that screen, mine is completely different. I'm using Windows XP on a laptop (because the DVD reader/writer is broken on my Windows 10 PC). It is the latest version, do I assume it's the XP ? Any help most welcome, Chris

What player software? Old versions of VLC did not understand PGS subtitles from Blurays, but that was fixed over a decade ago.

I'd need to check that.
