I just backed up a copy of a region 1 DVD with DVDShrink. Making it region free. That part's fine. What worries me is that in the process of doing this, a message came up on the screen saying I had to change the region and my drive would allow me to do this 4 times. Of course, I had to change it back to region 4 when I was finished so now I can only do this two more times. So here are my questions: a)What is this all about? b)What happens if I do change it twice more? c)Can I override it? d)Is it my system orDVDShrink? (In other words can I just download DVDShrink again and start from scratch?) Any help would be appreciated.
