Why does my Roku give me copy protection warnings?

Episode 1246 (2:17:21)

Curtis from Virginia

Curtis has been watching Leo on Roku and lately he's been getting HDCP errors for unauthorized access. Leo says that's just nuts. There's no reason why that's on there. But it's also problematic because everything needs to be HDCP compliant. It's clearly a spurious message because Leo's podcasts aren't copy protected. He can power it off and unplug the Roku, then plug it back in. But it's clear that something is confused.
