I have Samsung DVD Rom 616Q Firmware F403, I updtd it to E403 using a Samsung utility, Discinfo shows No Lock detected, Nero Info tools shows No Lock, No region lock, when I insert an orginal DVD Grease locked at region 1, the above things show region lock detected. Does this mean that I have only four more region locks to go before I get locked with the last region? Does this mean that My DVD Rom is not Region Free??? Thanks!!!
