ticoalu & others wondering about RPC-1 or RPC-2, please refer to the following link
Regional Playback Control ·RPC II for complete information.
Since the DVD-ROM drive is a 12x or 16x read speed and includes dual laser diodes for CD-R playback
Manual, we can assume it is a quite recent drive. According to RPC-II specification, DVD-ROM drives manufactured after Dec 31, 1999 shall be RPC-II.
For reference -
Phase I RPC implementations allowed computer-based DVD playback systems to implement RPC functions in the playback system, so long as the RPC functionality was closely coupled with the CSS authentication and decryption functionality. Thus, the host computer was allowed to implement the RPC functions through software or hardware playback systems. During Phase I, only one region was allowed to be set for any given computer DVD playback system.
Phase II, in contrast, allows the region of the computer-based DVD playback system to be reset by the consumer but requires that the manufacturer of the DVD Drive implement the RPC functions in firmware in the drive itself. In general, this means that the consumer may reset the region of his/her DVD Drive 5 times (and may have this 5 times resetting capability re-established by an authorized service center an additional 4 times after purchase).
Now if I hear about anybody trying to bypass the Region Code or using DeCSS, I'm gonna have to send the DVDCCA after you...
