My WD TV Live can via a SR Receiver and HDMI switch, connect to either my TV or my projector.
However, if the WD TV starts up and detects the TV, it won’t output anything when I switch to the projector and vice versa.
I have to power the WD TV completely off in order to make it detect when I switch to another unit. It is not enough just to put it in standby.
It is quite annoying having to switch it completely off, since it takes a long time to start up and it also compiles my media library when powering up, adding to the start time.
I never had that problem with my old media streamer (mede8er mini) in the same set up.
