WORTH NOTING ON TV

FRIDAY David Copperfield (CBS, 8-9 p.m.): Magician Copperfield is about the best in the hokey, age-old business of producing ``oh-h-h's'' from audiences - even worldly-wise ones. In ``The Niagra Falls Challenge,'' he pulls several impressive stunts, including being chained to a raft - in front of an audience - then shoved into the rapids above the falls. Great Performances (PBS, 9-10:30 p.m.): ``Dance in America'' offers `Six Balanchine Ballerinas,'' a closeup - livened with fascinating and sometimes historic dance footage - of six women who cumulatively worked with the late choreographer for four decades.

MONDAY The Presidency, the Press, and the People (PBS, 9-11 p.m.): A bombastic title for a fascinating format: Ten former presidential press secretaries - a job whose function has expanded dramatically over the past several years - talk about what it was like to deal with everything from leaking stories to lying to the public.

TUESDAY Frontline (PBS, 9-10:30 p.m.): ``Born in Afica'' grimly documents the last months of Uganda's singer-musician Philly Bongoley Lutaaya - a cultural hero who wrote the song used as the program's title. After announcing he had AIDS - in Africa 90 percent of it is spread heterosexually, by blood transfusions, or from mother to child - Lutaaya led a national educational campaign against the disease before he died.
