NBA semifinal (NBC, 7-9:30 p.m., EDT): If a seventh game is needed in the best-of-seven series, the Indiana Pacers will face the Orlando Magic at Florida's Orlando Arena in pro basketball's Eastern Conference Final.

In the drama category, there are enough strong new plays and revivals to make competition more suspenseful. Tom Stoppard, Terrence McNally, and other writers, for instance, are in the running.

Crusades (The History Channel -- simulcast on A&E -- 9-10 p.m.): Terry Jones of ''Monty Python,'' the renowned British comedy troupe, retraces the course of one of the 11th-century armies that moved East across Europe to reclaim the Holy Places in the Middle East.
In this four-part series, aired on consecutive nights, he meets both Christians and Muslims, from scholars to artisans to aristocrats. Islamic and Western culture, past and present, are explored.
