Can I use Plex to play back my iTunes movies?

Jay thinks that the AppleTV is too long in the tooth and is thinking about using Plex instead. Can he use it and still watch stuff bought on iTunes? Leo says no. They're all copy protected so he can only play them back on iTunes or an Apple device. This drives Leo nuts because pirates know how to defeat it. But having said that, Plex is great.
