This appears to be the same as the 2006 BBC series Nuremberg: Nazis on Trial
http://www.imdb.com/title/tt0814234/?ref_=fn_al_tt_6 and http://thetvdb.com/?tab=series&id=172171&lid=7
Same nbr episodes, same episode titles, same actors in the 2015 AHC version as listed by IMDB for the 2006 version
AHC's contribution appears to be limited to:
- cutting each episode down to ~44 minutes (from ~60 minutes AFAICT)
- changing the narrator (Bill Graves, where the 2006 BBC version has Matthew Macfadyen according to IMDB)
- various logos etc
Now, I do not have access to the 2006 version, so there could be other differences, or errors in the IMDB listing, but I doubt it
That seems to be very little "original work" to qualify as a new series regardless of the impression AHC gives in their summary
