Sue Thomas F B Eye was airing on BYU-TV, the cable channel from Brigham Young University
(at least I see it listed as such on my dish).
Family Affair has turned up on the weekend binge on DECADES TV. I don't think it is
running regularly anyplace.
Unsolved Mysteries had an FAQ on their webpage stating that the show is not available online
nor airing anyplace "due to guild (union) rules that existed at the time those shows were produced".
Since Rescue 911 was produced at the same time I presume the same answer would apply.
