Two miniseries, two newcomers and today's New York Marathon highlight the week. WTTG's "Shaka Zulu" is a five-night story focusing on the Zulu warrior who helped his people form a new nation. "Echoes in the Darkness," a two-nighter on CBS, details the true story of a murder involving a principal and teacher from a high school outside Philadelphia. Look for the arrival of NBC's "Beverly Hills Buntz" and ABC's "Sable." The Redskins face Buffalo today, the Caps and Bullets both see action this week, and thousands compete in the 18th annual New York City Marathon.

THURSDAY A DIFFERENT WORLD at 8:30 on NBC

BEVERLY HILLS BUNTZ at 9:30 on NBC "The Cosby Show" picks up an episode that had been postponed, but "A Different World" comes up with a new one: Denise Huxtable's little sister Rudy visits Hillman College and chooses Denise's nemesis, Whitley Gilbert, to admire above all others in the dorm. Norman Buntz (Dennis Franz) survived the death of "Hill Street Blues" after all and turns up in Beverly Hills with former snitch Sidney Thurston (Peter Jurasik). Buntz, who began his tour on "Hill Street" by playing bad-cop Sal Benedetto, will try to make it in Southern California as a detective. Like "Mama's Boy," starring fellow "Hill Street" actor Bruce Weitz, "Beverly Hills Buntz" is scheduled only monthly until the network kills off a regularly scheduled series -- in TV/sports parlance, it's a designated hitter. Guests: Eileen Heckert on "The Cosby Show" (8 on NBC). MOVIES: "A View to a Kill" (8:30 on ABC), with Roger Moore as James Bond.

FRIDAY GREAT PERFORMANCES at 9 on PBS

AIDS: CHANGING THE RULES at 10 on PBS Morning notes: Phil Donahue celebrates two decades for his talk show today with an anniversary celebration featuring video clips from his favorite interviews.

It's part of a new Great Performances miniseries, "Tales From the Hollywood Hills," which will feature works by F. Scott Fitzgerald and Budd Schulberg on Nov. 13 and 20. Then tune in for an hour-long special aimed at adult heterosexuals. Ron Reagan Jr. is the host, with model Beverly Johnson and salsa star and actor Ruben Blades ("Fatal Beauty," "Millagro Bean Field War"). The format, using explicit street language at times, begins with a 25-minute film suggesting steps individuals can take to minimize the risk of contracting AIDS, and Reagan shows you how to use a condom. That's followed by a half-hour studio discussion moderated by Judy Woodruff and featuring the following panelists: Dr. David W. Fraser, president of Swarthmore College; Dr. Harold Jaffee, chief AIDS epidemiologist at the Centers for Disease Control in Atlanta; Dr. Helen Singer Kaplan, director of the Human Sexuality Program at New York Hospital-Cornell Medical Center; Dr. Gary Noble, AIDS coordinator for the Public Health Service, and Dr. Reed Tuckson, commissioner of public health of the District of Columbia. Believing this program to be especially significant, WETA will rebroadcast "AIDS: Changing the Rules" at 11 p.m. next Monday through Thursday and at 2 p.m. on Friday. Guests: Eddie Albert beginning a special role on "Falcon Crest" (10 on CBS). MOVIES: "His Girl Friday" (11 on 22/67). SPORTS: Bullets vs. Atlanta Hawks (7:30 on 20).
