I just got a new display (Samsung, Tizen software). Now, whenever I switch to the Roku input (either selecting it via the Samsung remote, or if the Roku wakes up the display, or if I just unplug and then plug in the Roku), it will automatically start the Roku Channel app, and start playing some random movie or show or something.
I removed the Roku Channel, and the next time I tried it it started CNBC and started playing something on there. But the time after that it just reinstalled the Roku Channel app and launched it (but didn't start playing anything).
At first I thought it was just when I used the Samsung remote, and maybe the remote was sending some errant signals. But it does it even if I don't use the Samsung remote. For example if the display is off and I hit the Home button on the Roku remote, the display will power on, and Roku will launch the Roku Channel app and start playing something.
What is happening? I've never seen anything like this before.
