re: Questions
The DVDs can be played all over the world, yes.
The Apollo 17 DVDs only show the TV pictures on the surface of the Moon and the landscape was more interesting.
The Apollo 16 DVDs also show 16mm films (taken from a camera they had on the Moon and those images are the sharpest ones) but it's a fraction of all the images. The landscape wasn't as interesting except when they went down to the "Big Black Rock".
