So I have a Roku Express (I think). I have a 65" Vizio in my living room. It has 5 HDMI ports and will only play Roku on #2. While watching any live tv app, it will constantly jump back to the home screen. If I enter the app I was watching prior, it basically goes back to a few seconds before the exit on whatever show I was watching. I have a 32" Vizio from my kids room. The Roku never jumps to home screen on this tv. Any ideas?
Also, it should be noted this does not occur on the symptomatic tv while using Netflix, but occurs on basically every other app.
