Video: How Do the Discs Look?
Not great. Taken from rotten-looking 4x3 sources (looks like videotape, folks), Campbell's interviews here look fuzzy, smeared, and, well, ugly. Even with a ground-floor restoration, these wouldn't look astonishingly good, but even so, more could have been done here to curb the compression artifacting and overall blah-ness of these transfers.

Audio: How Do the Discs Sound?
These Dolby Digital 2.0 tracks work a bit better. Again, these are simple discussions between Moyers and Campbell, so there's not much in terms of dinosaur battles or spaceship warp drives kicking in, but as straightforward presentations of talks, these could be worse.
English SDH subtitles are included.
