Hask12 - sorry if I was too technical. To answer your question, this new box will only display existing captioned programs. The problem this addresses is cable and satellite boxes which either (a) don't display captioning, or (b) make it very difficult to display and control captioning. Regarding DVD's, that's a tough question - many DVD's, but not all, have captioning. To further confuse things, many DVD players, but not all, pass along the CC signal on the output connector.
