It's some of the model devices that are doing this now. Just started recently. It's not cables. My old roku premiere doesn't do this or my roku tv built in apps. My roku Express is the only device this happens to... And now I'll tell you why... it's the video preview on certain apps that does this... I switch back to my roku Premiere device. Works fine. And fyi.... My voice remote works with my premiere that never offerd this feature or remote originally. And I tried turning off the video preview on the troubled apps? Doesn't help. Change your device.
