What I was trying to explain is that I feel that odds are extremely low (like zillions to one) that all these HDMI/HDCP problems are caused by HDMI cables or even the connections, especially when those cables have been supplied by Roku. Since Roku devices are having these chronic problems, as evidenced by thousands of postings about it online, the devices themselves must be remarkably unreliable. Since the cables work on everything else, including other streaming devices with HDCP protection features, I think it's time for Roku to stop blaming the connections and cables, as though that's the only possible problem. Consider also, my Roku was working without problems for a year, then these errors started showing up after the update of 10/19/23. Modern cables and connections don't have much of a history of suddenly becoming faulty. Generally, when components are plugged in, they continue to work for years if not indefinitely. Despite that, I went through the recommended unplugging and replugging the HDMI connections and had it no effect on the frequency of error 020's.
Regarding apps, the problem appears on all of them, including those providing non-HDCP content.
My theory is that you folks sent out a software patch a year ago which resolved the problem, and recently did another update that unpatched it.
I also wonder about HDCP that only intermittently detects the issue, often letting the content play through without problems. That in itself suggests that your HDCP technology is flaky. Either the content protection is only functional for a minute or so every hour, or some glitch (non connection related) is causing "false positives," which resolve momentarily. I don't know if it's helpful or not, but usually, just before the error appears, the sound starts to distort and there are occasional screen flashes before the notice appears on the screen.
Rebooting reduces the frequency of errors. If I don't reboot, they can come every 15 minutes or so. When I reboot, it'll play for an hour or two before the error shows up again. Would that be the case if it a cable was at fault? A faulty connection can't adjust the frequency of it's fault based on reboots.
I did order a replacement device, as I'm running out of patience and hoping the problem may have been addressed surreptitiously. Sadly, my spouse seems to be addicted to Roku because of the earplug feature. I'm spending more time on a Fire Cube.
