I work at a speciality video & DVD retail store in CO, and get essentially every new release and re-release foreign films on DVD. The only Rohmer's I've seen on DVD are "Clair's Knee", "Pauline at the Beach", "Full Moon in Paris" and "The Marquise of O". I'm not a huge Rohmer buff so I'm not sure if those are the ones you're looking for, but I don't think that boxed set exists, at least not yet.
