About This Combo Drive
This Combo Drive is a RPC2 drive and according to DVD-Forum, PC
chip must be designed into DVD-ROM drives to record how many
times a user has changed the region code. Once the limit of 5
changes is reached, the drive won't allow you to change the region
code any more. It means the code will be locked and only those DVD
titles of the same region code could be played afterwards, so set the
code carefully.
