WORTH NOTING ON TV

* SATURDAY

Pavarotti in Central Park (PBS, 8 p.m. to about 10:15 p.m., E.T.): Anyone who's seen a Pavarotti concert on TV knows that his magic definitely works on that medium, and a live Pavarotti concert like this one practically justifies the medium all by itself. The way the great operatic tenor embraces a crowd seems to extend to viewers at home, and this occasion - his first solo performance in New York's Central Park - should be a prime example. So what if the voice isn't quite what it used to be? The big cro wd will still provide the explosive enthusiasm familiar to viewers of previous Pavarotti TV concerts.

The program includes his time-tested repertoire, with plenty of Verdi and the traditional Italian songs whose mere titles bring roars of anticipatory delight from audiences. Members of the New York Philharmonic will be under the direction of Leone Magiera, who often works with Pavarotti in Europe. On the same bill is the Harlem Boys Choir and also the brilliant young Italian flautist Andrea Grimminelli, who frequently appears with the tenor on tour. (The taped concert will be aired internationally on Sunda y.) * SUNDAY

Havana (NBC, 8-11 p.m.): Network debut of the 1990 Robert Redford vehicle set in Cuba during the 1950s near the end of Batista's rule. A card shark (Reford) comes to Havana for a big game and gets involved with a woman, as the corruption and violence of those times seethes around them. Alan Arkin, Lena Olin, and Raul Julia are also in the cast, and the director is Sidney Pollack, Oscar-winner for the 1985 film "Out of Africa."

Curacao (Showtime, 9-10:23 p.m.): Another vehicle, this one for George C. Scott, in a movie made for Showtime. He stars as a vaguely Joseph-Conradish sea captain who is now a recluse and runs a bar on the Caribbean island of Curacao, where he loves to regale patrons with lurid tales of his past. His true past he'd rather not expose, but events threaten to do this as a murder mystery develops. William Petersen plays a security officer at the American consulate.
