Hi
There are many programs availble that allow you to change the region code or make it region free. If the movies are not too old
DVD Shrink will do the job plus compress it to fit on a single layer disc and its free.
DVD Fab Decrypter may be needed needed to be used first to remove the copy protection if it is a fairly new movie. There is also a free version of this too. Check out the "Copy DVD" forum on this site to learn more.
