Can anyone help me. I need the firmware upgrade for my denon dvd3910 as it currently will not handshake with my projector. The current firmware is 6609-5. I have spoken to customer support at Denon who have advised that I need a firmware upgrade but two weeks later I'm still waiting for the discs to arrive and getting somewhat frustrated. Does anyone have the discs and if so could they send them to me? Ps this is my first post so forgive me if I've done anything wrong.
