Example du jour: I tried "casting" something to my Chromecast while everything was powered off. Sure enough, the TV and amp turned themselves on (win!) but the amp didn't bother to switch to the Chromecast (fail!). When I disconnected and reconnected to the Chromecast, *then* the amp switched to it.

I imagine this might just be "your amp is old; get a new one", but it seems silly to replace an otherwise perfectly functional amp. Now, if one of the Japanese amp builders decided to integrate GoogleTV into their amp, getting rid of all their awful internal UI craziness, *then* I'd switch in an instant.
