You can hack your dvd recorder by this follow:
Switch on DVD recorder and make sure no disc is in the tray
Press the "SYSTEM" button on the remote control
Change the "REMOTE CONTROL USED" from "DVD RECORDER" to "DVD PLAYER"
Store this change (important)
On the remote control press "PLAY,1,5,9" (the display on the recorder will now display 11 dashes)
Now, using the remote enter the following 121 212 005 255 (last few digits won't appear on the screen - but don't worry)
Press "PLAY" on the remote
Switch off the recorder and wait for a few seconds
Switch recorder back on and using the remote control press the "SYSTEM" button. Change "REMOTE CONTROL USED" back to "DVD Recorder". Remember to store this change
So that your dvd will turn into multi-region as you can use any disc from anywhere else...
