There is conflicting report about the new Pioneer DVD-114. Some drive look like to not have the RPC pins, other have it (and can be made region free). Currently, many DVD-ROM drives have no region codes because they are manufactured based on RPC(Regional Playback Control) Phase1. Based on the RPC-1 system, MPEG decoders must have region codes, while drives do not have to have it.
Based on RPC-2 system, drives must also have region codes protection. Any DVD-ROM and DVD-RAM drives must be manufactured and shipped based on RPC-2 from January 1st, 2000. This is mandatory for manufacturer. This year is a transition period..Also check this page for more info… NULL
