One of the reasons that a lot of us own Oppo Blu-ray players is because they're relatively easy to unlock so you can play Blu-rays and DVDs from multiple regions. I originally unlocked my BDP-103EU with a hardware modification kit but if I'd known there was a software version I would have probably gone for that instead. I recently found out about a software unlock kit that's available from this website. It will cost you €89, which is the same as a hardware mod kit, but it's completely software based. From what I've discovered it's highly effective, adds a bunch of other features and won't invalidate your warranty either. I also like the way that you just select the region via the Disc Menu Language submenu. Anyway if you're an Oppo owner who is thinking of getting their player unlocked, you might want to check out Blu-ray Solution.
