OK, got it. Thanks for the explanation, but it might have been clearer
to be more explicit in the first place. I'm not sure how many of us
would know what NVR means at the drop of a hat. Google doesn't mention
this interpretation in its first couple of screens. Even a specialist
site such as http://www.acronymgeek.com/NVR (which gives 90 possible
decodings of NVR), doesn't have this one.

Anyway, let's just leave it at that. In my initial response to the OP I
missed the fact that we were talking about an ISO install, which makes
all the difference.
