I have a DVP-NS55P region 1 DVD player as well. I tried the trick described a few pages earlier. It seems our friend forgot to mention the very last step: HOW TO GET OUT PROPERLY OF THE PROGRAM, so our changes are saved. Can anyone tell us the missing step to follow? I have a chinese DVD I'm filled with desire to watch (An Animal Face-Off DVD, one of my favorite shows), but I can't do it because it's a region 6 one. When I bought it, I was sure it would work, because I have quite a collection of asian DVD's here that work in my player. But I learned too late that they worked because they were "region 0". So, if anyone here knows the final step to make all DVD's play on DVP-NS55P, please write it down right here.
