It's Sony, thus a different "They," and I bet you dollars to donuts "They" won't pay to use "Georgia On My Mind" on the DVDs. "They" will also not remaster the episodes, as it was shot on film with post-production done on tape, and they will probably look horrible. And don't think they won't sneak syndication-cut copies on some of them.
But back to GG,
—NBC's tapes were stereo
—Prime Network's tapes were stereo
—Local syndication tapes were stereo
—Lifetime's tapes are stereo
—Some of the episodes available for viewing uncut at the Museum of TV and Radio are stereo
But the DVDs are mono. I just don't know what to say.
