Any more information as to how to get hold of the firmware update to fix the odd 6.1ES problem with certain discs? My R2 Terminator 2 makes popping noises (DTS 6.1ES) when you pause and resume playing the disc. I also have a problem with lord of the rings, which is detected as DTS 3/3 (discrete) it plays fine in AFD mode (5.1), but won't play in 6.1 mode. According to US forums, the firmware has been updated for the DA5ES to 1.74, I have 1.4 in my reciever, checked by rotating the knob under the flap to the left until it's displayed. The reciever has a serial port on the back for this perpous, perhaps I could do it myself, or has anyone got a phone number for somone in Sony that knows about the problem and can offer a solution?
