From what I can fathom, Sony make two versions of this excellent player: one for the US and another for the rest of the world. The US version has progressive scan. I am a complete novice at home cinema and am researching this kit for my first setup. Does progressive scan make such a difference that I should import the US one? I'll be using it in conjunction with a projector (which accepts prog scan) so I understand that picture imperfections are emphasised even more - should this affect my decision? Ususally the advice this kind of question receives is "test them out side by side" but obviously, a model only sold in the US is going to be hard to demo!
