I don't bother with any of that stuff. I bought a wire that has a mini-stereo plug on one end and the red & white RCA stereo plugs on the other. I plug the mini-stereo plug into the iPod, and the red & whites into the CD input in my Yamaha receiver, and voila. No need for a dock or an "iPod compatible receiver" or anything else.
Of course, if I could hook up the dock, that would be sweeter, cos then I could get the wireless remote control.
