i thought there would be some software that can convert it at least
Nope. The DRM prevents it.
well... if you really, really, really wanted to burn the movie I am sure you could get a video screenshot program, start playing the movie, video screeshot the whole thing, and then burn the video screenshot you just took... why would that work? if you had the time...
That would work, but it would be a pain....
Again, The DRM will likely prevent you from doing this.
