I have a common 700 MB avi file, a movie, for which I have a subtitle in my language and I use KMPlayer 126.96.36.1995. The problem is that although I load the subtitle, it is not shown. This happens only at this movie. I even tried to rename the subtitle to have the same name as the movie, to be loaded automatically.
I tried to play the movie and load the subtitle in other players and it works fine.
So I guess it's KMPlayer's fault somehow.
