I noticed it yesterday on my roku 4 I think when I had max recording quality set. I think it went away when I used the 720 5 mbps setting. It might have been on my roku 3. Not sure. I switched a bunch of things around yesterday while trying out the roku 4 off and on. I’ll try to test more. My TV is old and 1080i, so at some point I was switching the output on my roku 4 from 1080P to 720P.
