Jim, I am also a big Netflix fan, you can actually set up different "accounts" within your own account, for different family members, each with its own queue. Anyways, I get tons of documentaries, since I either dont have the TV time or the cable channel, I catch up with the programs in Netflix, some examples (all are MULTIPLE DVD series):
Shootout!
Battlefields
The War machines of WW2
The History of Warfare
Great War Planes of WW2
Great Battles of ww2
Aviation Library
Roaring Glory warbirds
on the "wet" side of things:
The Great Ships Series
War in the Pacific
Battle Stations
I mean you get the drift... also look at individual episodes of Nova, History Channel, there was one of Cameron's Bismark expedition, the photography is fantastic.
Movies, whats missing from the older stuff? mmm Das Boot? midway, sand of iwo jima, so many.. in case you missed it, I would reccomend Glory (ACW)
There is also a book, hang on....
Brassey's Guide to War Films by Alun Evans (2000), ISBN 1-57488-263-5
250 pages of war films listings, just a short summary of each, everything you can imagine (until 2000 that is

Ran, cant forget that one!
5 star movies include The Alamo, All quiet in the western front, Battleship Potempkin (1925), Bridge over River Kwai...
