Just Dance 3 [Region Fix Free][ISO]
This is achieved by way of region-locked DVD players, which will play back only DVDs encoded to their region (plus those without any region code). The American DVD Copy Control Association also requires that DVD player manufacturers incorporate the regional-playback control (RPC) system. However, region-free DVD players, which ignore region coding, are also commercially available, and many DVD players can be modified to be region-free, allowing playback of all discs.
Just Dance 3 [Region Free][ISO]
DVDs sold in the Baltic states use both region 2 and 5 codes, having previously been in region 5 (because of their history as part of the USSR), but EU single market law concerning the free movement of goods caused a switch to region 2. European region 2 DVDs may be sub-coded "D1" to "D4". "D1" are the UK only releases; "D2" and "D3" are not sold in the UK and Ireland; "D4" are distributed throughout Europe. Overseas territories of the United Kingdom and France (both in region 2) often have other regions (4 or 5, depending on geographical situation) than their homelands.
Region-code enhanced, also known as just "RCE" or "REA", was a retroactive attempt to prevent the playing of one region's discs in another region, even if the disc was played in a region-free player. The scheme was deployed on only a handful of discs. The disc contained the main program material region coded as region 1. But it also contained a short video loop of a map of the world showing the regions, which was coded as region 2, 3, 4, 5, and 6. The intention was that when the disc was played in a non-region 1 player, the player would default to playing the material for its native region. This played the aforementioned video loop of a map, which was impossible to escape from, as the user controls were disabled.
The scheme was fundamentally flawed, as a region-free player tries to play a disc using the last region that worked with the previously inserted disc. If it cannot play the disc, then it tries another region until one is found that works. RCE could be defeated by briefly playing a "normal" region 1 disc, and then inserting the RCE protected region 1 disc, which would now play. RCE also caused a few problems with genuine region 1 players.
Many "multi-region" DVD players defeated regional lockout and RCE by automatically identifying and matching a disc's region code or allowing the user to manually select a particular region. Some manufacturers of DVD players now freely supply information on how to disable regional lockout, and on some recent models, it appears to be disabled by default. Computer programs such as DVD Shrink can make copies of region-coded DVDs without RCE restriction.
However, most NTSC players cannot play PAL discs, and most NTSC TVs do not accept 576i video signals as used on PAL/SECAM DVDs. Those in NTSC countries, such as the United States, generally require both a region-free, multi-standard player and a multi-standard television to view PAL discs, or a converter box, whereas those in PAL countries generally require only a region-free player to view NTSC discs (with the possible exception of Japanese discs in most European countries, since they are in the same region - this means European region 2 users could import Japanese discs and play them on their players without any obstacles.) There are also differences in pixel aspect ratio (720 480 vs. 720 576 with the same image aspect ratio) and display frame rate (29.97 vs. 25).
Usually a configuration flag is set in each player's firmware at the factory. This flag holds the region number that the machine is allowed to play. Region-free players are DVD players shipped without the ability to enforce regional lockout (usually by means of a chip that ignores any region coding), or without this flag set.
However, if the player is not region-free, it can often be unlocked with an unlock code entered via the remote control. This code simply allows the user to change the factory-set configuration flag to another region, or to the special region "0". Once unlocked this way, the DVD player allows the owner to watch DVDs from any region. Many websites exist on the Internet offering these codes, often known informally as hacks. Many websites provide instructions for different models of standalone DVD players, to hack, and their factory codes.
Older DVD drives use RPC-1 (Regional Playback Control) firmware, which means the drive allows DVDs from any region to play. Newer drives use RPC-2 firmware, which enforces the DVD region coding at the hardware level. These drives can often be reflashed or hacked with RPC-1 firmware, effectively making the drive region-free. This may void the drive warranty.
Some drives may come set as region-free, so the user is expected to assign their region when they buy it. In this case, some DVD programs may prompt the user to select a region, while others may actually assign the region automatically based on the locale set in the operating system.
Most freeware and open source DVD players ignore region coding. VLC, for example, does not attempt to enforce region coding; however, it requires access to the DVD's raw data to overcome CSS encryption, and such access may not be available on some drives with RPC-2 firmware when playing a disc from a different region than the region to which the drive is locked. Most commercial players are locked to a region code, but can be easily changed with software.
The Xbox, Xbox 360, PlayStation 2 and PlayStation 3 consoles are all region-locked for DVD playback. The PlayStation 2 can be modified to have its regional-locking disabled through the use of modchips. Although region locked on film DVDs and film Blu-ray Discs, the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X are region free for video games, though add-on content on the online store is region locked and must match the region of the disc.
Blu-ray Discs use a much simpler region-code system than DVD with only three regions, labeled A, B and C. As with DVDs, many Blu-rays are encoded region 0 (region free), making them suitable for players worldwide.
Blu-ray regions are verified only by the player software, not by the computer system or the drive, not like DVD regions. The region code is stored in a file or the registry, and there are hacks to reset the region counter of the player software. In standalone players, the region code is part of the firmware. Some Blu-Rays are region-free.
The Australian Competition & Consumer Commission (ACCC) have warned that DVD players that enforce region-coding may violate the Competition and Consumer Act 2010. A December 2000 report from the ACCC advised consumers to "exercise caution when purchasing a DVD video player because of the restrictions that limit their ability to play imported DVDs." The report stated, "These restrictions are artificially imposed by a group of multinational film entertainment companies and are not caused by the existing differences in television display formats such as PAL, NTSC and SECAM [...] The ACCC is currently investigating whether Australian consumers are paying higher prices for DVDs because of the ability of copyright owners, such as film companies, to prevent competition by restricting imports from countries where the same (authorised) video titles are sold more cheaply." In 2012, a report from The Sydney Morning Herald revealed that region-free DVD players were legal in Australia, as they were exempt from the Technological Protection Measures (TPMs) included in the US Free Trade Agreement. Under New Zealand copyright law, DVD region codes and the mechanisms in DVD players to enforce them have no legal protection. 041b061a72
