I live in Sweden so I have subtitles with the letter "Ä?" but it doesnt show up in BSPlayer properly which is MUCH annoying,look at this screenshots to see for yourself:
With BSPlayer:
With DivX Subtitle Displayer:
That´s the only annoying problem I have found with BSPlayer so I have to use DivX Subtitle Displayer for the moment,
but except that bug BSPlayer is definitely the best player out there.
