This post is beyond awesome

Hello.Pal version dvd's - I'm trying to back up a copy of Friday the 13th Pt. VII. It's a region 2 dvd and it says that I must change my drive to a region 2 code. It says that this can be changed 4 more times. o.OI wondering if there's any harm in trying this out. Is it pretty easy to revert the code back to a region 1 code?Any help would be much appreciated and thanks to anyone in advance.
