For what it's worth, PBS has an app[1] for Apple TV, and it has much of PBS' content.

With that said, the general problem of certain services being restricted from/to specific platforms is extremely frustrating, and will only get more painful as exclusives become common.

From my experience on the AppleTV3, the PBS Kids channel/app had very limited access to past episodes. Is this different on ATV4?
