I also tried some blu-ray movie on the official XBMC (for Windows), I disabled subtitle when playing the movie and pressed the stop to go back to the file list, and chose the same movie to play agian, the status of subtitle was enabled.

So it seems that's the design of XBMC.

Correct me if I was wrong.

That sounds like a bug. XBMC/Kodi should remember if you've disabled subtitles for a specific video.

Wolly wrote that he used official XBMC for Windows. Because this is working well I think he used a video with forced subtitles.
If he will try it again he will see that there is a difference between the good behavior of XBMC for Windows and wrong behavior of Vidon Gotham XBMC.
