Content creators care about publishing schedules and expiry dates - how long the content is available on iPlayer. That's their primary concern. What exactly is DRM protecting them against? It's not geo-blocking, that's done on the server. There's no "download button" that suddenly appears on iPlayer if the content isn't encrypted. So please remind me what protective benefits DRM brings the rights holders and content creators? Keep in mind, it's trivial to screen capture video on any half-decent computer. Anyone "determined" enough simply needs screen capture software and then hit record.
