We purchased a Roku Express 4K to replace a Sony Blue Ray player that we used to access our Wi-Fi network to watch online content, Netflix etc. We connected the Roku, and we through the setup procedure, and everything appeared to be working correctly until we went back to cable TV.
When we did that, we found that the cable box remote (pressing just about any button on the cable box remote) will cause the Roku to take control, and switch the video source back to whatever we were previously watching on the Roku.
We went though the remote pairing procedure, and that seem to fix the problem. However, we had to remove power from the Roku to fix another problem, and now the cable box remote issue has returned.
We do not want the Roku remote to control the cable box or TV. Likewise, we do not want the cable box remote to control the Roku.
Does the Roku lose it's remote pairing information after a power cycle ? Why does the cable box remote interfere with the Roku ? If we can't get this problem fixed, the Roku is useless for us.
