Might want to try restarting the Apple TV or even resetting it.
Try hooking it up straight to the TV to see if the cable is good. My Apple TV is pretty sensitive when it comes to the HDMI cable. Unplugging it and plugging it back in sometimes corrects the handshake issue as well as turning my AVR on and off. I have a HK AVR 1600 BTW.
