Merry Christmas, Teletubbies!

MERRY CHRISTMAS, TELETUBBIES! Tinky Winky, Po (1999, Warner, 90 mins., unrated) It seems appropriate that the hugely lucrative British critters should introduce toddlers to the holiday's more commercial traditions, from tree trimming to gift getting. Parents will rejoice at the merciful absence of the PBS series' most irksome gimmick — instant replays of long video segments whenever Po and Co. demand ''Again! Again!'' REEL GOODIES (0:32) The vacuum-cleaner-like Noo-Noo commits a no-no, sucking up all of the 'tubbies' decorations -- then sneezes them back out, beautifully festooning their futuristic underground lair. THE LAST DETAIL Despite running only an hour and a half, Merry Christmas, Teletubbies! is split up on two festively colored tapes: One's red and the other's green. B+
