I may not know what I mean either;-0)
I no longer use a TV, I use a HD monitor. I have a couple of cable
company HDVRs and they each have the option to display
subtitles/closed-captions, which usually appear with descriptive and
dialogue texts. The display, a Westinghouse 42" monitor, has no CC
option which I can find. I also have an OPPO DVD player, and find no
CC option but there is an option to default subtitles on in a language
of my choice.
Most DVDs which I have are English spoken language. Among those most
have an English subtitle track, which appears similar to CC in that
descriptive data accompanies dialogue. But, when I play one which
does not have an English subtitle track, I'd love to be able to play a
CC track. I sampled only a few of the collection since this thread
began and find none for which the player, the monitor, or the software
players on the PC will offer a CC on/off option.
So, I was curious of the title of the DVD (or any title of an English
DVD so CC encoded) so that I can either check my shelf or the well
supplied library near by, to tinker with how I might display these
titles.
Does that help clarify my confusion?
