About This Drive
This DVD±R/RW Writer is also a RPC2 DVD-ROM drive and the first region code
will depend on the DVD title you play. You are allowed to modify the region code 5
times
(including the initial one). After the fifth alteration, the region code will be
locked and only those DVD titles of the same region code could be played
afterwards, so set the code carefully.
