>>Region coding...<<
A few years ago my daughter came back from her "student exchange' trip from Germany. She had bought an armful of DVDs of her favorite with German subtitles/dubbing to help her with her German.
You know where I am going with this. 8^>
I had to explain region coding to her...
I would certainly never suggest using this for anything other than discs you already own, but a program called DVDShrink will let you rip a DVD to your computer's hard drive and get rid of all of those pesky little things like region coding, FBI warnings, locked out menus, etc.
I use this to put together DVDs with trailers, cartoons, etc., for "old fashioned movie night" at home.
