Page 6 details the Tools menu and Subtitles. Some DVDs do not have subtitles. Your post is light on details but in the USA you would return it for a working model.
I cannot get rid of the dvd player's closed captioning. I have a Samsung DVD E-360 player, but I must add that I had the same problem with a previous DVD player connected to my current Samsung HDTV. Ideas, anyone?
