turn off subtitles

Hi,

I have a movie that has subtitles within it. When I play it within Divx player, they don't appear (however, I can turn them on from the menu). When I play the same movie file in Front Row, the subtitles appear by default. I really don't want them there as the movie is in english anyway. I have no idea how to turn the subtitles off, could someomne suggest how to do it?

Cheers.
