Man, I have heard this "all the sudden" boo-caca from some TV personalities, and granted, they are only saying what they were taught to say by others around them, while growing up... BUT! it's supposed to be 'all of A sudden" being that 'a sudden' seems like it's being used as a noun... because it CAN be (and IS) used as a noun, i.e. "all of a sudden" ;) Truly it is used in it's correct and incorrect form... if you have to be anal about it (I am NOT saying that there's anything wrong with that btdubs), say something to the person that says it wrong... if you can live with it, then do.
