Many thanks for fixing this in MC32!
I just tried on on a couple of ripped to disk DVDs, and everything worked fine, then menu Audio and Subtitles language selection worked perfectly in both cases: menus with options that set both the audio and subtitle selection at the same time, and menus which have independent audio and subtitle language selection.
If I may, I would ask to keep the media files (mkvs, etc) language selection independent of the DVD language selection, just as it is in the new MC 32.0.18 version. Or at least to provide an option in the MC settings to have them independent.
Media files can have a lot of subtitle choices in them, so an automatic selection is useful, and it's something I use right now for them. But DVDs only have 2 or 3 choices, and I prefer to always make those choices in its menu, as sometimes the choices set both the subtitle and audio track at the same time (like audio commentary + subtitle commentary, or Japanese audio + English subtitles) and I like to do it like this than trying to fight with the automatic selection system and figure out which audio track goes with which subtitle track. Same for BluRay discs, I prefer to make a choice in the BluRay menu. This way both disc formats (DVD and BluRays) would work the same way, too.
