Is there any way of creating an MDR file ourselves? I mean probably with commercial software? It might be interesting to have an MDR with a single adresse, 2 adresses same city, 2 adresses samt street+city etc ... Guessing by difference is more efficient than to wade through half a gigabyte of data in an unknown format.
