Hi Dave, I am afraid, you won't find such a software hack. This kind of functionality is burnt into the main chip of the unit, and while there supposed to be a way to reload the firmware of the deck, I have not seen any modified versions yet (well, this does not mean too much anyway), nor any posts here or on other forums, that would discuss the how-to. Sony is known for keeping such proprietary firmware totally confidential, and hackers would only work on something that enjoys wide interest (i.e., when back in old DVD times, they hacked drives' firmware for region code, etc.). You may try to replace the main IC on the main board of the 440 with the one from a 640. I mean, if performing such a delicate rework is worth it for the end result.
