seen this site years ago, and forgot about it! but recently reminded of it, thankfully. also site seems bigger and better than i remember.
I know the cheap junk dvd players are region free usually, but the high end ones have the region BS, us in with the mexicans.
so if you are like me and buy rarer or unusual stuff from overseas that you cant get in 'region 4' off amazon ect. and have a nice locally bought region 4 player, and dont want to rip, shrink and zero everything, this can be very handy to say the least! worked for my LG perfectly and a denon i have.
