HI,
I think, it's version 5 behavior that subtitles appear on the movie and not black bars. It would be good if the behavior is like version 3 i.e if there is a black bar then subtitles should appear on the black bar and not on the movie.
Its doesn't matter, movie, songs, programs, events, resolution, format, laptop resolution, etc. Its simple... any/all medias played with version 3, if there is a black bar the subtitles appear on the black bar. And any/all medias played with version 5, if there is a black bar the subtitles appear on the movie.
Just play any video with subtitle and black bar, if there is no black bar then choose any aspect ratio, and play with version 3 and 5, you will see subtitles appear on the movie in version 5 and on the black bar in the version 3.
I forgot to mention, I mean soft coded or external subtitles.
Regards
