Just tune in to another channel with service 0 on and note how the captions look and then change CC to service 1 and note the difference, if there is any. It doesn't happen on every channel and I didn't mean to make it sound like it was a big deal. Usually it's just larger or different fonts with extra spacing between lines. It doesn't ruin the captioning experience and, to be honest, I'd bet most people wouldn't even notice. I'm hard-of-hearing myself and some of my family members are totally deaf (hereditary) so we've watched TV with captions since the 80s. You just get used to the way they normally look and when they're "different" it's noticeable.Could you please cite examples so I can be on the lookout?
