All, I just thought I would share this with you. The hack involves firmware supplied by Marantz (40MB) on a memory stick to the dealer. There are detailed instructions which basically involve installing special "change the region" firmware. You then set the region for DVD & Blu Ray (no region free BR). Then re-install the original firmware. There are also factory codes to enter. It is not a simple fix these days like it used to be (Arcam used to use open the draw & press 1234, etc.). I dint know if Berny deliverers, I certainly had nothing from him. Maybe you need to talk nicely to the shop you bought the Marantz from.
I purchased my machine from a local independent shop who I have purchased hi-end kit from for many years and this was all part of the service.
