She has absolutely no desire to do it.
You want her trained.
Ask yourself: who has control over her bladder and bowels? Is it you or is it she? All the begging, pleading, forcing in the world isn't going to get her going any quicker.
Remember that potty training is a complex act:
-knowing/feeling they have to go
-getting to the bathroom in time
-being able to physically take down pants
-being able to get on the potty and go
-wiping
-washing hands
Whew! That's a lot for a two year old! Not that she can't do it, but it is one of the first complex-task skills you're asking her to complete. Even with kids who are ready, accidents are inevitable. What happens when she can't do all the steps and pees/poops in her pants, doesn't make it in time, doesn't wipe and her undies are all dirty, doesn't wash her hands? Are you able to keep your cool 100% and live through, perhaps, weeks of trial and error? Because if you're not...you will only become frustrated that it isn't working and she'll feel like an absolute failure.
You certainly can start introducing potty concepts to her, like watching the videos (personally I hate the Elmo video - it's FORTY minutes long - but many love it), letting her watch you in the bathroom, talking through all the things she can do when she goes potty, etc.
But really it is up to you - if you're okay with holding her hand every step of the way and potentially getting frustrated because it doesn't magically happen, then by all means start. You might have better results, though, if you choose to let HER take the lead because after all she has total control over her bladder/bowels and there isn't much you can do about it (especially if she's okay sitting in her own waste all day).
