Rough guess off the top of my head:

Woody
Hitchcock
Lynch or Almodóvar in 3rd

I'll go 5 because well it is pretty close.....

Hal Hartley (10)
Sam Peckinpah (9)
Werner Herzog (9)
John Cassavetes (7)
Jim Jarmusch (7)

Alfred and Steven are way above all others (over 20 each) then I guess Buster Keaton. I guess in terms of pure hours of material, Ken Burns' is also in the running.

Jess Franco (32)
Lucio Fulci (27)
John Carpenter (19)

Clint Eastwood (22)
Steven Spielberg (19)
Joel Schumacher (16)
