DVD Region Code
A DVD title has a region code according to the international specifications so that it can be played
only in that specific region. DVD titles with a region code will only play on DVD drives with the
same region code.
A DVD drive is sold with an empty region code and the region code is set when the user inserts
a DVD title into the drive for the first time. Whenever a DVD title is inserted with a region code
that is different from that of the DVD drive, the region code of the DVD drive is automatically
changed to the region code of the DVD title. However, changing the region code of a DVD drive
is limited to 5 changes. After that, the region code is permanently fixed to the last region code.
