Not since "The Dream" erased a season's action on "Dallas" (in 1984) has a new-season premiere resolved a cliffhanger as dramatically as does the renamed "seaQuest 2030" tonight. The New York Philharmonic is also in good form on "Live From Lincoln Center."
"seaQuest 2030" (8 p.m.-9 p.m., WBAL, Channel 11) When last we left this series in the spring, the submarine seaQuest had just blown up on another planet and only Lucas and Dagwood (Jonathan Brandis and Michael DeLuise) had survived. Yet the Steven Spielberg show survived into a new season with a new title, reflecting the plot in which the vessel mysteriously reappears on Earth in the year 2030, 10 years after it disappeared. Michael Ironside also comes aboard as a new captain, as Roy Scheider cuts back appearances this season. NBC.
* "Live From Lincoln Center: New York Philharmonic Opening Night" (8 p.m.-10 p.m., MPT, Channels 22, 67) Strauss' "Don Juan" and works by Wagner, including the overture to "Die Meistersinger," highlight the gala evening from Avery Fisher Hall. Soprano Jessye Norman is the featured performer, and radio simulcasts are scheduled on WBJC-FM (91.5) in Baltimore and WSCL-FM (89.5) in Salisbury. PBS.
* "Melrose Place" (9 p.m.-10 p.m., WBFF, Channel 45) The melodrama reaches the 100th-episode level, rare for any spinoff from another show (in this case, "Beverly Hills, 90210"). Among the story lines, Jo and Jake (Daphne Zuniga and Grant Show) finally get back together. Fox.
* "Dateline NBC" (9 p.m.-10 p.m., WBAL, Channel 11) Film director Paul Verhoeven talks about his controversial new movie, "Showgirls," which has been tagged with a rating of NC-17 for subject matter and nudity. Has the film about Las Vegas night life gone too far? NBC.
* "The Naked Truth" (9:30 p.m.-10 p.m., WMAR, Channel 2) -- In last week's premiere, Nora (Tea Leoni) photographed model Anna Nicole Smith at the gynecologist's office. Striving for legitimacy, tonight Nora goes after Oscar-winner Tom Hanks, who appears as himself. ABC.
* "Law & Order" (10 p.m.-11 p.m., WBAL, Channel 11) Filling a void left by actor Chris Noth's departure, Benjamin Bratt joins the cast as Detective Reynaldo "Rey" Curtis, a technology-oriented new partner for Briscoe (Jerry Orbach). Sandy Duncan guest stars as the attorney for a student charged with murder. NBC.
* "20th Century With Mike Wallace: Hurricanes" (10 p.m.-11 p.m., A&E; Network) Good timing in the year of Felix, Humberto and Marilyn brings a documentary premiere recounting the most severe coastal storms of the century.
