No Subtitles

I am using the latest beta of DVDFAB and ImgBurn. Trying to backup my copy HSM 1,2,and 3 (so I can just keep a copy in the car instead of dragging them back and forth from the house to car and back, what a pain) Problem is that my kid wants to see the words but I can not get the subtitles to show. Other movies I’ve done subtitles show no problem but with the HSM ones don’t seem to work. Any one got any ideas.
