This is going to set you back several Disney dollars… (Part 4)
You can view Part 1 (Snow White and the Seven Dwarfs to Alice in Wonderland) here, Part 2 (Peter Pan to The Black Cauldron) here and Part 3 (The Great Mouse Detective to Tarzan) here.
Fantasia 2000 (James Algar, Gaëtan Brizzi, Paul Brizzi, Hendel Butoy, Francis Glebas, Eric Goldberg, Don Hahn, Pixote Hunt, 1999) - I don’t own this one on DVD. The R1 US single-disc edition includes a DTS track, commentaries and other bonus materials not found on the R2 versions. This and the 3-disc Collector’s Edition (bundled with Fantasia) are both OOP.
The Emperor’s New Groove (Mark Dindal, 2000) - I don’t own this one on DVD. All versions present the film in an aspect ratio of 1.66:1, accompanied by the original 5.1 mix. The OOP R1 2-disc Collector’s Edition features a DTS track not found on the other releases, but otherwise all 2-disc variants throughout the world appear to be identical. Avoid the various (also OOP) single-disc releases.
Atlantis: The Lost Empire (Gary Trousdale, Kirk Wise, 2001) - All of the various 2-disc Collector’s Edition releases present the film in its original 2.39:1 aspect ratio, accompanied by the original 5.1 mix in both Dolby Digital and, in English-speaking territories, DTS forms, plus a massive array of extras. There is also a single-disc R1 release, but at all costs avoid the R2 UK single-disc version, which features only a cropped 1.33:1 presentation of the film.
Lilo & Stitch (Chris Sanders, Dean DeBlois, 2002) - All releases present the film in an aspect ratio of 1.66:1, accompanied by the original Dolby Digital 5.1 mix. Virtually every territory except North America has a 2-disc Special Edition packed full of extras, with the R4 Australian release also including an English DTS 5.1 track and therefore being the best available version. At all costs avoid the R2 English and German releases, which have been censored (particularly the German release, which is missing upwards of a minute of footage). The UK versions also have a Gareth Gates song inserted over the closing credits.
Treasure Planet (John Musker, Ron Clements, 2002) - All releases present the film in an aspect ratio of 1.66:1, accompanied by the original Dolby Digital 5.1 mix. The R2 UK release also includes a DTS 5.1 track, making it the preferred version. Having seen both PAL and NTSC transfers, I would say that the PAL version offers improved detail while also exhibiting slightly more in the way of compression artefacts.
Brother Bear (Aaron Blaise, Bob Walker, 2003) - The R1 2-disc Special Edition includes two versions of the film, one corresponding to the theatrical presentation of the film (starting in windowboxed 1.85:1 before expanding to 2.39:1), and the other cropped to 1.66:1 throughout. The R2 UK version, meanwhile, comes on a single disc and includes only the cropped 1.66:1 version. According to Rewind, the R2 Norwegian release is also OAR. Both English-language versions also include a DTS track. Note that the R1 release has very poor image quality (extreme amounts of filtering).
Home on the Range (John Sanford, Will Finn, 2004) - Draw between all releases, which present the film in an aspect ratio of 1.66:1, accompanied by the original Dolby Digital 5.1 mix.
