WORTH NOTING ON TV

FRIDAY...Talking With David Frost (PBS, 9-10 p.m.): Ted Turner is the guest on the season opener of the series conducted by the man who may be TV's best "talking head." In light of today's faltering commercial networks and cable controversy, it's not a bad time to be hearing from Turner. The maverick media giant has stood the industry on its ear more than once - with CNN and many other ventures. Now he'll have a chance, at length and perhaps even in depth, to size it all up.

SATURDAY World Series (CBS, 8:30-11 p.m., E.T.): Game 6, if needed.

SUNDAY World Series (CBS, 8:30-11 p.m., E.T.): Game 7, if needed.

WEDNESDAY Great Performances: Paul McCartney's Liverpool Oratorio (PBS, 8:30-11 p.m.): Yes, it's a real oratorio - calling for 300 singers, eight movements, and elaborate orchestration. It also offers classical stars like Kiri Te Kanawa and Jerry Hadley backed by the Royal Liverpool Philharmonic Orchestra and Choir under Carl Davis, who is also co-composer. Filmed June 28 in England's Liverpool Cathedral, the massive work is having its world broadcast premiere, with radio simulcasts in most areas. Liverpool, where McCartney spent his youth, is the setting for the reflective, partly autobiographical odyssey as it explores McCartney's - and Everyman's - life. Before the performance, a documentary catches moments of rehearsal and lets McCartney reminisce about his early years a Beatle.
