Subtitles in MKV (x264, H264)

[neral]

Hello, now i can play MKV files with BSPlayer 2.15 : it's so great !!!!!

But i am french, so i watch MKV in english, but with subtitles in french, and BSPlayer have a problem with this....

BSplayer can display the subtitles, but :
- we can't choose the size
- we can't move up or down the subtitles
- in full screen, the subtitles are ALWAYS in the movie, even if i want them in the "Black Part" for 2.35 movies...
- for a 4/3 screen : if the video is 4/3, subtitles are perfect, but if the video is in cinemascope (16/9, 1.85, 2.35) the subtitles are "crushed" (size down in height, perfect in width...)
- inverse problem for video in laptop (screen 16/10)....

Sorry for my english!!!
