The BluRay Disc contains the R-Rated as well as the Unrated in very good quality. Although especially the second difference between the Unrated Version on BluRay and that on DVD does seem like censorship, it is not very likely that it actually is. What's more likely, is that the Seamless Branching is responsible for this flaw. With Seamless Branching several parts of a movie can be joined while watching, so that two versions of the same movie can be contained on one disc without actually storing two whole movies on the disc. Only the differing scenes are contained twice and are played during the movie in the proper spots without interrupting the movie. So in this case, it is very likely that the scenes simply have been forgotten in the production process.

As the Predalien devours the homeless woman in the sewage tunnel, alternative shots have been used in both versions. On the BluRay (just as in the R-Rated) we see the Predalien from behind, while on the DVD we see a close up of the lower body of the woman.

When Jessy is nailed to the wall by the Predators throwing blades, the DVD Version shows her lower body dropping to the floor on its own - along with the appropriate sound effects.
On the BluRay (just as in the R-Rated) she remains in one piece.
