‘Forced’ subtitles definitely work for BDMV folder playback for HD blu-Ray. E,g Mission Impossible Rogue Nation blu-Ray. I recently checked this for myself with this movie.
I can’t verify if the same applies for ‘forced’ subs on UHD movies, haven’t investigated this yet.
If the Oppo 203 respects the forced flag on mkv playback, you shouldn’t need to select anything, the subs should be displayed automatically. (If the mkv includes the relevant PGS subtitle stream)
You can check whether a particular movie has ‘forced’ subs via the web, there are documented lists.
Firstly, check if the original movie of one of the MKVs you are trying has ‘forced’ subs.
If the original movie has ‘forced’ subs and the Oppo 203 supports the forced flag in MKVs, the subtitles should appear automatically.
Otherwise, if the original movie has separate subtitles, you would need to select subtitles and the PGS stream for the relevant subtitles would have to have been selected for inclusion in the original mkv.
If the movie has embedded subtitles, these are merged with the video and appear automatically.
