No actually, DVD's from the US/Canada don't work in Europe, I have no idea why! My parents picked up a 4-pack of John Wayne movies last fall and were very disappointed not to be able to watch them. However, their Pavarotti concert DVD made in Europe was also sold here and worked when they got home, so it looks like maybe European DVDs work here but not the other way around?
Also, it depends on the player itself. They were able to watch the John Wayne movies on my brother's machine!
