Thanks for the speedy response. I'm sure just the fact that it's now uncut HD will definitely make up for the lack of playable extras in some minds.
It's not just PS3s, though. There are many players that will not playback 50hz material. Even some HD TVs will not display 50hz.
It's definitely something that, unless you've read something about it, brits wouldn't necessarily be aware of. I mean, the UK even had NTSC DVDs released, the prevalence of multi-format tvs and players... You'd think the whole world would work like that
Edit: I'm pretty sure the DVD wouldn't work on a PS3 either. It's the same 50hz/60hz, 25FPS/29.97FPS issue. However, most people who would import it, I'd hope would have a multi-region DVD player.
