My, my, my ... I go out of town for a few days and things get all out 
of hand ...

First an innocent question about region coding and a few 
misunderstandings of what's going on turns into a fight about copying. 
Let me throw my two cents worth of gasoline onto the fire.

Region coding has little to do with copying and almost all to do with 
marketing. It was traditional until very recently that Hollywood movies 
were released first in North America, six months later in Europe, and 
another few months later in Asia. The DVDs are released about six 
months after the movies in all parts of the world. The region codes are 
there to make it more difficult for Japanese consumers to buy DVDs of 
movies before the movies are released on-screen in Japan. Since movies 
are now released all over the world at pretty much the same time, the 
region-coding scheme is becoming irrelevant.

North American commercial DVDs are region 1 DVDs. Japan, Europe and a 
few other places are region 2. A region 0 DVD is region-free and can be 
played anywhere.

Blank DVD-R media has no inherent region. It can be set to any region 
when recorded. iDVD defaults to region 0. More advanced authoring 
software, such as DVD Studio Pro, lets you set the region when the disk 
image is created.

If you want a region-free software DVD player on your Mac, try VLC

Many (most?) hardware DVD players can easily be hacked into being 
region-free by pushing the "secret" sequence of buttons on their remote 
controllers. You Google the model number of your machine to find out 
how. Both of my Apex players and my Toshiba TV with built-in DVD player 
were easy to find. These hacks are there because the Chinese make these 
sets for the whole world and don't want to be bothered too much with 
worrying about where a certain model will be sold.

Region coding has nothing to do with copy protection. There is no copy 
protection on a commercial DVD other than the fact that commercial DVDs 
are double-layered and DVD-R disks are single-layered. This means that 
there's generally too much data on the commercial DVD to fit it onto a 
DVD-R. So, the movie must be copied and re-encoded to have a smaller 
footprint. This means the MPEG2 file on the original is re-encoded with 
with less resolution and missing sound tracks for the languages and 
sound formats you don't use.

There's plenty of software out there to do this--both commercial and 
free. The commercial software is faster and easier to use, but the free 
stuff works just as well. I don't want to get into the details here 
because KR will probably e-mail me an explosive virus, if I do.
