There is commentary in Thom Hogan's D7000 book on this. I believe you must set Aperture before turning on Live View. Then take the still or video. The limitation in Live View is that the changes to exposure settings must be made before starting Live View.
Perhaps somebody else here can elaborate. My use if Live View is only for still focus and a preview of Depth of Field, not for Movies or anything to do with exposure.
