DVD/Blu-ray release
The one-disc and two-disc versions of the Region 2 DVD were released in the UK on November 19, 2007, on both standard DVD and Blu-ray Disc formats.[56] The movie was released on DVD in Australia on November 21, 2007, and released on December 4, 2007 in the United States and Canada. The 2-Disc DVD is a "limited time only" release, in contrast, the Blu-ray Disc release will stay. The initial Blu-ray Disc release was misprinted on the back of the box as 1080i, although Disney confirmed it to be 1080p. Disney has decided not to recall the misprinted units, but will fix the error on subsequent printings.
