You're missing my point.
I just watched Get Smart - I turned on "SDH" and it came out it looks like English subtitles (or cheapy foreign subtitles). Because the text always stay in one place - middle/bottom of the screen.
I've already explained in different thread that there are two kinds of SDH out there - one shows text that appears at position where character speaks - that's CC-like SDH. "Foreign subtitles" would only appears in the bottom middle of the screen -
Universal Studio, Sony Pictures, Columbia Pictures, and Sony Classic Pictures are only ones that showed CC-like SDH.
