I finally had a sec to pull a key off the still you sent. Is the screen being buffeted by a fan by any chance? I think the dancing edges are the creases in the screen showing up and perhaps fluttering. You may need to use the blur feature in Keylight to pre blur the screen to diminish those.
Or you can pull two keys one for the dark greens and one for light. Or pull two keys one for the body of the person (clamp the heck out of it) and then do a roto matte (very loose) around her head, make a thick fuzzy line out of that mask and then use that as a mask. (basically a halo of the edge of her hair). Combine that with a thin green key that lets some of the screen show through. Then you can have a much less dense matte and you can screen that element in over top of the main chunky matte of her. Because its blonde hair it screens well and lets you keep all those split ends even though the matte isn't great/solid.
