Here the same. I've r connected through a denon x3100 to a plasma Panasonic. Zidoo turns on but not TV

I think Denon is problem here, because if you unplug Zidoo from Denon and just try CEC control between Denon AVR and TV it'll not work -> turning on TV will not turn on AVR (same with shutdown). Plugging HDMI from Zidoo directly to TV, CEC is working as expected. Shame that Denon didn't do better job in supporting this feature.

I have found Denon's attempts at cec is very poor, it is also I believe responsible for a lot of handshake failures I have on my system.

Surely you are right guys, but with ps4, chromecast and a Sony bluray player, no problem using cec through denon avr
