>Expect a boom in sales for TiVo—or lots of viewers staring at the remote, paralyzed with indecision. As of Thurs., Sept. 21 at 9 p.m., ABC is moving its top-rated Grey's Anatomy from Sundays and putting it against CBS's powerhouse CSI. The crime series, in its seventh season, is counterprogramming with young McDreamies: Rocker John Mayer will perform on the season opener, and soon after that Kevin Federline
will make his acting debut in a guest role. The show's creative team "are juiced," says CBS entertainment chief Nina Tassler. NBC, meanwhile, already blinked, moving Studio 60 on the Sunset Strip, announced for the same time, to Mondays.
