Thanks k1241, this is the most helpful you have ever been. And no weird picture to boot!
Actually the standard DVD release includes both aspect ratios too:

But at least he tried.
And it looks like each ratio shows something and crops something, not unlike films shot on Super 35. You get a little extra on the sides, or top and bottom, but not both.
