As I recall, the web site pretty clearly marked which Unity 1.x features were Pro only (e.g., Windows deployment and water shaders), but I’m confused about 2.0. Although it’s not mentioned on the Shadow Light or Audio Video pages, the “what’s new” page says that shadows and video playback are Pro-only features.
Shadows, videos and the Asset server. Plus all the 1.6.x Pro only features.
