@Valenciano, do you know, why the MPC-HC ignores the sub track preferences? MF Ghost plays default spanish subs, but i set it to 'not use default or forced' and selected eng for english subs, just it does not works. mpv config works, fine, just mpc have something what mpv no, so i can't just discharge, before i updated, it has issues with av1, but not with track selection, now it is upside down. both players have pros and contras, but i don't like unexpected effects. According your name, i understand the default language settings, i have no complaints about, i am just annoyed why my player fuck me off.

Problem solved: MPC-HC-> wastebin, replaced with MPC-BE.
