I agree with 5 Little Monkeys - drop it for a bit and see what happens. Whether she's messing with you or just not quite developmentally ready for it, it sounds like it may have become a bit of a game for her. She gets to sit on the potty for hours and get stories read to her and watch movies and has all of Mommy's focus on her whenever she is on the potty...why would she want to pee on the potty and give all that up? She is still young. If you took a break for a bit and started up in a month or two, it might be a smoother process?
