you might be able to flash your dvd drive to a firmware with region-free ability, and perhaps some other perks 😉 such as if you have a Pioneer 117D in your powermac/emac you can flash it to a region-free, unlocked rip speed, 16x, etc etc. 108. i'm sure there are a lot of other drives you can do this with. does void your drive's warranty though, but not the rest of the computer afaik
