Matter of fact, the recently-released US DVD contains the Unrated Version. Besides several trivial extended plot scenes, the main differences are the nudity scenes, which really upvalue the movie. In almost any scene, where a girl shows her boobs, the TV Version contains alternate more harmless footage. The splatter scenes remain unharmed and are pretty bloody for a tv production, even though they're rare. A detailed comparison between both versions with pictures can be found here.
