OK, I think I understand better now.
a) If I make an analogue recording to my hard disk it has no SCMS bits set,
or is classed as 'unlimited digital copy'.
b) If I make the same analogue recording to my MD the SCMS bit is set to
'digital copy once'.
What surprised me was that the 'unlimited digital copy' from a) was
preserved when subsequently copying between MDs.
The SBLive seems to be "SCMS-compliant" and does apply SCMS to recordings,
if I make a digital recording from CD to hard disk I can copy the resulting
wav file to MD but subsequently copying from that MD gives 'NO COPY', so it
is acting in the same way as the MD.
It differs from the MD in that it establishes 'unlimited digital copy' for
analogue recordings. In my view the SBLive! is doing it correctly and the
MD is not. Why shouldn't someone be allowed to make multiple digital copies
of their own analogue sourced material?
I have to confess to some naivety here, I hadn't appreciated the
generational loss digital to digital MD copy. In my head I imagined that
the MD knew it was another MD sending data and just copied the data, then I
thought about it some more. Doh! What's missing of course is a genuine MD
to MD copy, faster than realtime with track and/or disk name data sent.

I wasn't talking of copying digitally sourced material (CDs), just analogue
stuff recorded off the radio straight onto hard disk.
