Look for the "Services" menu. In digital television, the "Services" options replace the old "CC" choices:
Services 1: Captioning in the program's language, such as English. This was called CC1 in analog televisions
Services 2: Captioning in Spanish (previously CC2 or CC3)
Services 3 through 6 are for captions in other languages, edited captions, and other uses to be determined later.
