I previously did recording to disc from a camcorder so I changed the dubbing to DV/D8 dubbing. I am trying to go to the simple dubbing now because I want to record from a VHS family movie tape to a disc. It will not allow me to change to simple. DV/D8 dubbing is highlighted but I can not get it to go to simple dubbing with the up and down errors. It is greyed out.
