Nuforce oppo extreme bdp-93 and "the regions"

Hi Goners!

Please explain to me what regions a,b,c and regions 0 to 6 mean and if there is a "universal" machine available.

I'm anxious to purchase a dvd/cd player from Oppo but want to understand these codes....Thanks to all!

The regions are geographical areas and are specified by the player to discourage international piracy of movies. On the older Oppo players there is a way to disable the region selection. You should be able to find this on the Oppo website-that's where I first saw it.
The new Oppo players require a hardware mod to be region free.
