After the last ROKU Ultra update I did,, not the new (11.5) one released this week. We started to get this HDCP 020 error. Well I still have a Denon 4311 CI, connected to my ROKU and my Panny TC-P60ZT60 Plasma. And this only impacts ROKU and HULU Live. I can go from my ROKU to Disney +, Amazon Prime, NetFlix and never get the error. And at times, if I selected on HULU a show not from the Live TV area, it works. Happens on the other TV's a SONY 65" OLED with no AVR just ROKU ULTRA. Per ROKU, all you have to do is unplug your HDMI cable and plug it back in and bingo it works. I've tried all kindas of HDMI cables even the ones that came with the ultra and it still happens. Freaking weird. HULU saids its a ROKU fault and ROKU says its a HULU fault. I say come one, someone fix it, since it worked great before the ROKU update and my HULU has been to date way before this occurred.
