I'm having HDCP problems with a Sony Playstation 3 and Apple TV when connected via HDMI through a Marantz 1603 AV receiver to a Panasonic GT50 plasma tv. Everything is brand new and all units firmware are up to date including the playstation, apple tv, marantz receiver and panasonic tv. If the Sony Playstation 3 and Apple TV are connected directly to the TV I have no problems. Problems only start when connected to the TV through the Marantz receiver. For a while everything works. Then the next day nothing works and I receive the HDCP error message, or a blank screen. OK, here is the catch, and I figured this is what was going to happen even before contacting Marantz and Panasonic. Each claim that it is the others problem. So where does that leave me. Any suggestions would be greatly appreciated.
