Place raisins in small bowl, cover with very warm tap water. Let stand 5 minutes to plump, then drain.
Meanwhile, in large skillet, heat 2 tablespoons butter over medium heat. Add pears, brown sugar, cinnamon, nutmeg and plumped raisins. Cook 8 to 10 minutes or until pears are very tender and almost all liquid is evaporated, stirring occasionally. Spread mixture on small rimmed baking pan or plate and place in refrigerator 15 minutes to cool (this step can be done up to 2 days in advance).
Preheat oven to 400 degrees F. Melt remaining 2 tablespoons butter in microwave. Place a stack of 3 phyllo sheets on parchment paper on work surface. Make a second stack of 3 phyllo sheets and place it so it overlaps the first stack by about an inch. Mound the cooled pear filling along one of the long sides of phyllo dough. Roll up like a jelly roll and transfer the parchment with strudel to rimmed baking pan.
Brush strudel with melted butter. Score the dough into 1-inch portions using a serrated knife, but do not cut completely through the strudel. Bake 20 minutes or until golden brown.
