While I own and use a Panasonic BD30 player (mostly for playback SD DVDs because I'm a old-film collector) and it does a great job of upscaling older DVDs, including those I've dubbed on my Panny EH55, I may soon have access to a Sony DVD SD DVD player and a "projector" to which I can attach the Sony player to output "large" images on various handy walls. I've discovered somewhat belatedly that my EH55 has recorded and I've subsequently dudded to DVD-Rs films with Close Captioning. Although it took a long time to discover this, I found it quite accidentally when I went back to check my Panny plasma display manual and found that if I could selected "CC on" in "set up" and used the EH55 as the plaing device, the CC "subtitles" magically appeared. I did discover that it doens't work with HDMI connections, hence playing a CC-enhanced DVD on my BD30 doesn't work and my S-video connected EH55 to Pnny display does as long as "CC on" has be set up.
Finally, my question: Do any, few or many SD DVD players such as a Sony "read" CC coding (perhaps through use of the remote) so that it can be projected through a (probably code-neutral) projector onto a wall? I have some friends and relatives with various levels of hearing loss who could benefit from the CC option.
