NOW IS THE HOUR: CBS’ “48 Hours,” focusing on how Orange County is handling the AIDS crisis, has personal meaning for its co-producer, Rob Hershman (F1). . . . Hershman, 39, has AIDS and is physically deteriorating. Tonight’s show, on Channel 2 at 10 p.m., is called “The Killer Next Door.” Says Hershman: “The people on this show are people who were absolutely convinced that AIDS was somebody else’s problem.”
