Like many I have DVDs from more than one region of the world as I travel a fair amount
Like many I really hate the fact that my Macbook limits me to 1 region even if they kindly let me change it 5 times
During a search for RPC1 firmware (something I've done on PC's many times) I found an argument I tend towards, having region protection actually encourages people to Pirate movies, why? becuase you can always play a pirate movie in any drive as it has no region, whereas a shop bought one....
I have been making region free copies of my DVDs for this reason and to allow me to make new copies when the kids wreck them but it's nice to have a region free drive when travelling around and now I do and I'm very happy about it.
HUGE thanks to ben11 who wrote the firmware and was kind enough to package it up and make it dead simple to use...
