Works:

Notes:
All extras should play fine unless specifically noted.
Cross of Iron: Menu will default to German. Extras will not work due to PAL SD.
The Deer Hunter: Bonus disc boots as well.
Ice Cold in Alex: Sylvia Sims interview and John Mills home footage won't play due to PAL SD. Trailer and gallery play fine.
My Darling Clementine: Second disc works as well.
Outlaw Star: All four discs work.
Pickup on South Street: Disc will “Stop” but press “Play”, “Stop”, and then “Top Menu”
Ran: Bonus disc will not load…menu might be locked at PAL.
They Live: Bonus disc boots as well.

Won't work:
