Not all movies are released at the same time in all countries. They usually are released in the US first, Europe and Japan next, etc. A movie may actually be released on DVD or VHS in the US before it hits the theatres in some countries.
Regional playback controls are thus an attempt to keep DVD sales from eating into theatre revenues in countries where theatre release is significantly later in time than it is in the US.
I don't agree with it, but that's the reason.

I kinda bought Hollywood's "we want to stagger DVD release dates because we need to stagger cinema releases because we don't have enough prints to go round" argument until I noticed this for myself a couple of months ago (not having really paid much attention to DVD until then...)
This is basic economics; if you're able to artificially segment your market, you'll optimise the total revenue by charging the most each segment will pay for your product. Without region coding, europeans like me would probably be importing all our DVDs from S-E Asia or the US where they're cheaper.
Playing the DVD game ensures you'll get screwed by the content publishers because the rules have been set by them entirely to their advantage. I've chosen not to play (apart from region-free discs such as music...)

However, Canadian dollars cost less than US dollars. This is why US people should import all DVDs from Canada and never pay for them in the US, because the MPAA is just trying to segment Canada/US (which, considering NAFTA, shouldn't happen) for greater profits.

The reason for phased release is simple: the very high cost of duplicating movie prints (each complete set for a 120-minute movie costs about US$2,500 to US$3,000 and you have to make about 6,000 to 8,000 prints for a blockbuster movie; you also have to factor into the cost of shipping each 35 mm print set weighing 210 pounds each for a 120-minute movie).
With the development of blue-spectrum LED lasers in the last few years, a theatrical-quality digital movie could probably fit on a single 300 mm optical disc; given today's technology to master and duplicate optical discs it'll probably be substantially cheaper to master and duplicate 8,000 optical discs than 8,000 film prints, not to mention shipping costs being a very tiny fraction of a 35 mm movie print!
With that substantial drop in duplicating and shipping costs simultaneous worldwide release of blockbuster movies may become the norm, not the exception.

Perhaps another thing to consider is that sometimes they have to edit a movie to comply to whatever regulations they have in a particular company. There are equivalents of MPAA in other countries, too.
One more thing to consider might be, in relation to the above, each country may have their own distributors and depending on whatever the suit in the distributors think, they might want to edit. This could add some time between the releases.
Not that releasing at the same time all over the world is not impossible, but it is true that the preparation for a release in a different country can take extra resources.
On a bit off topic issue, I hate when local distributors change the titles. It's not just a matter of translating English title to German or Japanese (well, I have experiences only in those countries). They sometimes stick (sometimes extremely silly) ENGLISH title to movies that laready had an English title. Recent examples I encountered were: Miss Undercover for Miss Congeniality (couldn't spell, so I figure why they changed the title), and ``Crime is King'' for `3000 miles to Graceland.'' (Is there any law in Germany that prohibits the use of English system? BTW, the quarter pounder of cheese is called Royal TS in Germany. And yes, they sell beer in McDonnald's.) I feel pretty embarrassed when no one knows a popular movie that has an English title

The original idea was to prevent importing movies on DVD from other regions before they actually hit cinemas locally. The point has become somewhat vague, because many discs are released only on some region, so many people have to resort to importing to get all the stuff they like. Interestingly, lately many blockbusters have opened at cinema almost simultaneously worldwide, which is definitely a good development. I wouldn't be surprised if this was at least partly because of the DVD importing still being possible despite region codes.
It seems they wanted to put something to replace the PAL/SECAM/NTSC barrier.
That barrier still exists on DVDs, but it's easier to overcome than with VHS. There are PAL and NTSC discs. Every PAL player can also play NTSC discs, but only some NTSC players can play PAL discs. If component signal is used (RGB is very common in Europe) you don't have to bother with color encodings, only whether your television can sync to 50/60Hz and display all the lines needed.
Is the NTSC stuff encoded on the DVD or is it an artifact of the conversion from digital to analong of the image?
Picture on DVD is fully digital MPEG-2, hence it has no NTSC, PAL or SECAM color encoding. Picture resolution and FPS still match either NTSC or PAL (SECAM has same specs as PAL, so there are no SECAM discs), because almost every display device used with DVDs still uses them. NTSC resolution on DVD is 720x480, while PAL is 720x576. Player handles 2:2 (PAL) or 3:2 (NTSC) pulldown on film material, and is also responsible for generating actual NTSC/PAL/SECAM color encoding if something else than component signal is used in connecting player to the display device. Needless to say, using component signal gives the best image quality you can achieve without going progressive, because it requires no additional signal format conversions after DA-conversion.
It's also good to note that because of the slight differences between NTSC and PAL discs, well-encoded PAL disc has better picture and smoother movement than well-encoded NTSC disc.
Re:Pet Peeve and question. (Score:1)
Since NTSC is about 30fps (well 29.97) and PAL is 25fps they record DVDs in different formats i think (lets ignore SECAM). I thought a much smarter solution would be to store the film at 24fps on the disk (ie cinema speed) and then do the conversion in the DVD player itself. Since allot of new TVs can show both formats, it stands to reason that you could build tvs to show 24fps. Also, lots of newer displays have grown up with DVD - plasma and all that, so they could have designed them for 24fps. Not only that, but a good deal of people watch DVDs on their computers that can certainly play 24fps. Maybe im wrong, i don't know.... also, the tv-out on my computer will let me show mpegs etc. on my tv screen (PAL - old) at different speeds with no flicker.. I think its just another example of stupid old formats and conventions.
Region encoding is much more than a format barrier replacement. Its simply there so the they can get more money. Staggered releases and different prices, its all evil capitalist/corporate pig stuff. The whole thing sucks

They do store the film at 24fps on the disc. The difference between a PAL disc and an NTSC disc is the resolution. PAL is 720x576 and NTSC is 720x480. The player converts the 24fps MPEG stream into 50fps or 60fps for the telly.
Be aware there's an incredible problem with the frame rate conversion. NTSC is 3:2 (odd frames twice, even frames thrice) which converts 24 fps into 60fps neatly. PAL is 2:2 (show each frame twice) which converts 24fps into 48fps. But PAL TVs are syncing at 50fps! So PAL DVD players actually show the movie a little bit fast to keep the frames syncing. This pitch shifts the audio track enough to be irritating, especially if you are playing DVD music (meaning music on DVD, not DVD-A).
Fortunately if you know the problem you can work around it. Some DVD players can output a bastardised format called PAL60. This is the PAL colour encoding at 60Hz. Almost any modern Australian TV supports this bastardised format.
Though an even better solution would be consumer-grade multisync TVs. Then you could sync the TV at 24fps and ignore the upsampling process. I don't know if any consumer-grade DVD player can output 24fps.

Even truly lossless (bit-for-bit reproduction) can be achieved with better than 2:1 compression, which would make 5 hours of CD music (just under 1.5 Mbit/sec bitrate) take 1.5 Gb, so reaching 6:1 shouldn't be a huge problem IMO.

Laser Disc Disadvantages
Laser Discs are too expensive for the average consumer to own. With the exception of MCA, and Warner, most Laser publishers have raised list prices to $40.00 and up for a first-run movie. Worse, many titles are only available as "special box-set editions" at prices over $100.00. To justify the price, these box sets often include CD soundtracks, posters, books, and other stuff you may not want.
Laser Discs are large, heavy, and fragile. Great care must be taken in storage to prevent warpage, jacket damage, and deterioration of the disc's aluminum coating. With even the best of care, a few poorly manufactured discs will loose their aluminum reflective qualities over time, resulting in increased video noise. This problem is aggravated by many publishers who refuse to take defective discs once they have "gone out of print". Caught in the middle are the dealers (like us) who have angry customers on one side and suppliers refusing defective returns on the other.
Laser Discs are "hard encoded" in NTSC video. Even though many LV players have S-video outputs, all laser discs, exhibit a characteristic "crosshatch" distortion caused by the NTSC color subcarrier. This is most noticeable in small text, where the letters seem to be "floating" amidst background of moving fine-grain diagonal mesh. Since all NTSC broadcasts have the same distortion, many Laser Disc owners don't notice the distortion until they compare it with component video or true S-video.

In my opinion one of the fundamental changes which needs to occur in the educational system is to teach people how to critically differentiate accident or 'stupidity' from deliberate malice. Failing to do so grants malevolent people a license to mask their work as 'stupidly' and thus get away with it.
The reason that I put the word 'stupidity' in quotation marks is that the problem in the intellectual world is not intellectual weakness - the problem is the misapplication of intellectual strength. The strong in any field always blame the weak - not because it is the weak's fault - but because the weak can't prevent them from doing so.
It is easy to ridicule the weak - and it shifts blame from where it belongs - with the strong - to people who don't deserve it. If intellectual problems were caused by intellectual weakness then surely dirt is the cause of all intellectual trouble - since I know of few things dumber that dirt.
