Ugetsu -Mizoguchi: Was recently released on DVD, Region 1, I think.
Pickpocket - Bresson - Exists on Region 2.
Playtime - Tati - Exists on Region 2.
Stalker - Tarkovsky - Exists on Region 2
Spirit of the Beehive - Erice - Region 2
Vampyr, Ordet, Day of Wrath - Dreyer - At least the last two Dreyer films you mention are in the Criterion Collection.
Mouchette - Bresson - Region 2.
The Passenger - Antonioni - Was released in Japan on DVD, but now out of print. But you can get in on Ebay if you're lucky. Anyway, they say that they are planning to release it in the US soon. This is maybe the film I want to see most of all films I haven't seen.
Sansho the Bailiff - Mizoguchi - Not on DVD yet, but the BFI VHS has a great picture quality.

Many of the films that I have wanted to see for a long time is being released these days: Touki-Bouki, Vidas Secas, and The Killer of Sheep in December.

I want to see these films on DVD:
Manila: in the Claws of Darkness (Brocka)
Fate (Kelemen)
They Live By Night (N. Ray)
Berlin, Alexanderplatz (Fassbinder)
The South (Erice)
The Story of the Late Chrysanthemums (Mizoguchi)
Oshima and Imamura's films from the 60's (a few exists, but none of those I want to see the most)
The Puppetmaster and City of Sadness (Hou) - I think there is a "Puppetmaster" DVD, but I've heard that it's best to avoid it.
