Press the Pause button on your remote control. Using your remote control enter the code 3,1,4,1,5 and 9, At this point, a blue screen displays showing that you are in 'region altering mode'. Press the 0 button on your remote control for Region free. Press the Pause button on your remote control. Power off your player and wait a few seconds. Power on your player and your ready to go!

It worked for me (after a few false starts)

I live in Australia and have two Samsung DVD/VCR player recorders, DVD-VR375 and DVD-VR355. I could only play Region 4 DVDs until I pressed DVD, with no DVD in the units, pressed Menu then 76884, then 9, inserted a Region 1 DVd and it played in both units.
