Just have a quick question.i recently purchased an Lg gdr8163b DVD Rom drive. When i put a Dvd in it said that i have 4 chances left to change the region. I have used one to set to australia.What happens if i take my computer to another country and have to do the same thing?What happens when all the 4 chances are over?Can i make it unlimited? I also purchased a LG DVD Ram writer
