One other thing that needs to be addressed is the machinist VS Anydvd.
The machinist is free and works quite well, Anydvd is a commercial decrypter and works very well it's what I use in place of the machinist. if you are serious about getting all new releases on the same day they come out I would highly reccomend Anydvd to you.
I have been using Dvd neXt copy for a long time and I might add with the machinist plugin I have had a success rate of 98% on all new releases not bad at all either full disc or movie only one of the 2 ways will normally work!!
