Is it any coincidence that the Lifetime channel is launching its new show, "Lifetime Live," just after the much-ballyhooed arrival of its well-funded new competitor, Oxygen? Probably not, although Oxygen, which like Lifetime is aimed at women viewers, can be seen by only about 10 million cable subscribers, none of them in Kansas City. Dana Reeve (wife of Christopher) and ABC's Deborah Roberts (wife of Al Roker) are co-hosts for "Lifetime Live," which airs weekdays at 11 a.m. It's the first daytime talk show on Lifetime in five years. @ART CAPTION:Reeve (left) and Roberts @ART:Photo (color) >>>
