Okay now let me ask you something, is it really region free? Because, I was always wondering about that BD. On the cover it says it's Region B and some do say it's locked in B, but others say it's region free. Since you live in UK where both are kinda mixed, maybe you can give me a hands-on proof that it runs on Region A device as well.
I can not really give you hands-on proof since the UK and Germany are both Region:B. All I can say is that my copy(bought in 2008 ) has no specific region label. This usually means it is region free. I guess over time they could have introduced a region specific version.
