I to would like a way to prevent accidental exit of this app.
I have elderly parents I am setting this up with on a NV Shield..and they are very not tech savy.
I was able to use a Button Remap app to force the new Netflix shortcut button on remote to launch Channel instead, so that kinda helps if they back out or hit the Home button.
At least Channels, when u suddenly leave the app, or go home, it does kill the tuner stream from my HDHR Prime....something that a Roku would not do with Emby app. (Was told by them that it a limitation of the locked down OS on Roku that prevents them from properly informing server of the data stream ending...cause locked tuners...bad thing).
