I am getting Leopard soon and am planning on doing a clean install. I was thinking, I have many DVD's from different regions and have never had the guts to change the DVD region on the computer. Now that the computer will be brand new soon (in a way) will i be able to change DVD region's before-hand like crazy. Will I be able to go through the 5 changes and then when I do a clean install, will I get those 5 back again??? That's all. Thanks.
