[mythtv-users] Captions: TV's CC vs. DVD's Subtitles, one button?

[Greg Grotsky]

A long, long time ago (years and years) we noticed that the "captions"
button on our remote (which just hits 'T') only worked for TV when it seems
it previously worked for both DVDs and TV. I just now realized that there
are separate functions for subtitling and closed captioning.
Apparently, closed captioning is for TV while subtitling is for DVD. I've
found that there are ways to program TOGGLECC and TOGGLESUBTITLE but I
cannot make them the same key, myth complains that the key is already being
used for the other option.

I really want one button that turns on captions for any video playback
(DVD, TV, or anything else). Is there a way to make this work?
Also, what is teletext? Do I care about it in the US?

Thanks,
-Greg
