Hi Robert,
The link you sent me has the FW update for a bluray player not for the Azur 651r receiver. I had already checked in the CA site but didn't find any FW for this receiver.
Current FW information for the 651r is as below. If anybody has knowledge of a newer FW please let me know.
Firmware: 1.46 / 1.45 / 1.09 (MCU / HDMI / DSP)
Regards,
Jose Antonio
