I searched ALOT online and it seems not many know you can control a PS3 with your Onkyo remote!
1. Ensure in your HDMI SETUP that RIHD over HDMI is ENABLED.
2. Ensure that within the Playstations settings under SYSTEM SETTINGS --> CONTROL OVER HDMI is set to ON.
3. Now on your Onkyo remote (I'm using a 509 amp) press and hold display and whatever your ps3 input is e.g mines on top left button BD/DVD. so I press and hold DISPLAY and BD/DVD buttons for about 3 seconds red led will come on on remote now simply key in the Remote code 32910 this is one of the (ONKYO DVD REMOTE CODES)
MOst basic functions for the bluray/DVD control work
Up, down, left, right, select, play, stop, pause, FF, RR, menu, quite playback, and most importantly.....
YOU CAN POWER ON and OFF the ps3 from your onkyo remote too!!!
