TONIGHT'S MUST-SEE

"Dancing With the Stars," 7 p.m., ABC. Here are the final performances with no sure winner. Judges have raved about Helio Castroneves (race-car driver) and Melanie Brown (Scary Spice in the Spice Girls). Viewers are fond of Marie Osmond. Last Tuesday, Osmond survived and Jennie Garth didn't. Now the three finalists will each do two dances — one chosen by the judges, the other free-style. Then viewers vote. Tomorrow's finale, which includes Celine Dion, names a champion.

"Notes From the Underbelly" season-opener, 8:30 p.m., ABC. As Andrew and Lauren await their baby he finds that his assertiveness is a turn-on for her. Meanwhile, Julie and Eric have a nanny who makes them feel excluded. It's an OK episode with some funny spurts.
