Subtitle size

Hi, I have an Samsung LN32D550 TV, and even with the subtitles settings set to the large one, the subtitle is yet too small, I'd like to suggest an option to choose the size with using pixel units like any other program, or make it even larger. Or if there is a way to change it's size via profiles.xml, how do I change it? thanks!
