SOURCE: Unlock codes for Pioneer DVD player

Pioneer DV-667A

Converting the player to Multi-Region:

Requires the use of a Palm Pilot w/Palm OS 3.0 or later and the OmniRemote Pro from http://www.pacificneotek.com/
(Other PDAs using Palm OS and compatible with the OmniRemote Pro from http://www.pacificneotek.com/ can also be used).

1. Program the Palm Pilot/OmniRemote. For instructions on programming the Palm Pilot/OmniRemote click How to Program the Palm Pilot.
2. Power on the DVD player without any DVD in the tray.
3. Keep the programmed Palm Pilot close to the IR port of the DVD player.
4. Start the OmniRemote program.
5. Place OmniRemote in TV mode and tap the "0" button on the OmniRemote.
6. The DVD player will power off.
7. Power the DVD player on again. Check the Region-free status by playing a DVD.

Step 1) Download the pioneer firmware here http://www.pioneerfaq.info/index.php?question=Firmwares

The site says the firmware only works on region 2 players. For this model it worked for my region 4 player in Australia

Step 2) Burn this file to a CD-ROM with name PIONEER as per these instructions - http://www.pioneerfaq.info/english/burn_guide.php

Step 3) Load the CD and your DVD player with ask you to flash the firmware. It says press play to start but instead HOLD DOWN ENTER during the entire process. DO NOT switch off your DVD during this time. When the tray opens take the CD ROM out but keep the DVD on. The flashing can take up two to three minutes. During this time HOLD DOWN ENTER ON THE REMOTE. The entire time!

Step 4) The DVD player will reboot. The tray should be empty. It will then load the tray back into the player. If the signal is disorted switch on and off.

Your done! Should work.

The most complex way of region freeing a DVD I have ever endured! :)
