Comment (by Andrew-R):

 tried tsMuxer. it can remux PGS subtitles from MKV (for example from
 sample from comment №11 at https://trac.videolan.org/vlc/ticket/6324) into
 something xine/mplayer recognize as BD disk.

 tsMuxer require either config file per run, or GUI (but I don't have qt5,
 so I just used command line)
 My two attempts at using it at https://yadi.sk/d/_LYvNL4N0aSZuA

 Mplayer may require -demuxer mpegts and/or "-lavdopts wait_keyframe" (from
 https://lists.mplayerhq.hu/pipermail/mplayer-
 users/2014-March/087262.html). May be my examples just too short for
 seeking working correctly by default?
