If you are using rca inputs from the 3.5 mm jack on the ipod, you should be able to select an audio only source, such as CD and still keep you picture, but I'm not sure if this works or not. It used to work on my old RX-V1600. Or you could just copy music to your PS3 hard drive and play music in the background while you play, as long as the game supports it. I know you can do this on the 360, since I do it all the time, except I'm not playing music from the hard drive, it's streaming over the network.
