My parents region free DVD player (also hacked a while back) died so I started looking for a replacement. I went to local Best Buy on Rt. 46 in West Paterson, NJ and purchased Philips DVP5990 DVD player which I then made region free the following way:
press 1 3 8 9 3 1
press up/down key to select 0
press menu to exit.
Turn your DVD play off. Turn it back on and enjoy watching DVDs from other regions.
