Primeiramente, eu verificaria se o disco realmente funciona em algo . Seja um reprodutor de DVD autônomo ou outro computador, não importa apenas algo .
Em seguida, eu tentaria extraí-lo do disco usando Mac the Ripper . Experimente diferentes configurações regionais.
Se você não encontrar mais nada que possa reproduzi-lo e não conseguir copiá-lo, os discos podem ser ruins.
Standalone DVD players
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.
Computer DVD drives
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. However, this usually voids the warranty.
In most computer drives, users are allowed to change the region code (i.e. change region code) up to five times. However, if the number of allowances reaches zero, the region last used will be permanent even if the drive is transferred to another computer. This limit is built into the drive's controller software, called firmware. Resetting the firmware count can be done with first- or third-part software tools, or by reflashing (see above) to RPC-1 firmware
Software DVD players
Most freeware and open source DVD players, such as VLC, ignore region coding. Most commercial players are locked to a region code, but can be easily changed with software.
Other software, known as DVD region killers, transparently remove (or hide) the DVD region code from the software player. Some can also work around locked RPC-2 firmware.
