Star Trek: Voyager (UPN, 9-10 p.m.): In celebration of the franchise's 30th anniversary, George Takei reprises his role as Capt. Hikari Sulu. When Tuvok's (Tim Russ) repressed memories begin to surface, Captain Janeway (Kate Mulgrew) mind-melds with him to trace the source of his memories. The two find themselves on the USS Excelsior as Sulu and the crew prepare to race off to rescue Capt. James T. Kirk and Dr. McCoy from the Klingon empire. (Trekkies will recognize events from the film "Star Trek VI: the Undiscovered Country.")
Takei is underused, and what starts as an interesting premise eventually peters out. "They were a different breed of Starfleet commander," Janeway muses of her predecessors Kirk and Sulu. Indeed. Beam me back, Scotty!
The Metropolitan Opera Presents (PBS, 8-11 p.m.): Placido Domingo takes center stage for this performance of Verdi's "La Forza del Destino."
48 Hours (CBS, 9-10 p.m.): The show looks back over a decade of news-gathering. Two highlights: Dan Rather revisits the site of a former crack house (reported on in 1989) to discover what has since become of the dealers and the police who busted them. Also, the show tracks down Benny, who was a homeless teen in 1989, and discovers what has happened to him during the past seven years.
Phil Donahue (ABC, check local listings): The talk-show pioneer signs off after 29 years and 20 Emmy awards.
Everybody Loves Raymond (CBS, 8:30-9 p.m.): Likable new comedy starring comedian Ray Romano as a sportswriter whose parents live next door. Ray's dad (Peter Boyle) likes to pick up their voice-mail messages, and his mom (Doris Roberts) rifles through their receipts with a glee that exasperates Ray's wife (Patricia Heaton). Comedian Brad Garret (who some may remember as the crazy auto mechanic on "Seinfeld") is noteworthy as Ray's slow-moving, idiosyncratic brother.
