Pioneer from japan same model as others dvr-111?

If I got a DVR-A11 from japan, would it be compatible in a computer with english Windows? Would it be any different to the A11 that will be released in europe? Scuse my ignorance here.

It will be 100% fine, there will be no difference at all. Enjoy the drive.

If i can get a friend to get me one I will. So there will be no problems if I got it and wanted to update it later on with firmware that was published for euro-A11 drives?

no problems at all.
