Anyone who has the Yamaha RX-V659, please try the following and post back what happens with your receiver.

With the remote control click the DTV/Cable button, set the surround decoder to PLII Music. Once you've done that, change to TUNER, set this surround decoder to Neural Surround. Now switch back to DTV/Cable and see if it switched from PLII Music (which was your setting) to Neural Surround the TUNER setting.

P.S. I need to know if I have a defective receiver while I still have time to exchange it. Your help would be greatly appreciated.
