“Can we use Captions with a HDMI source? We are unable to turn on the captions for a HDMI source (i.e. HD cable box). We have the caption option wen we are using another source (i.e. component, video). But when we are in the HDMI source we do not have this option on the menu and thus it appears we are not able to use captions for the HDMI source. Is this correct?”
