- This DVD is a combination of Thomas' Christmas Wonderland and Thomas' Snowy Surprise as they have the same episodes, songs and bonus features as well as both end credits, hence the title: Ultimate Christmas. Because of this, the title card from Thomas' Christmas Wonderland is used.
- This is the last DVD of several things:
- The trailer uses the Starz Home Entertainment logo while the actual release uses the Anchor Bay Entertainment logo.
- Writers Christopher Awdry, Jenny McDade and Paul Larson are not listed in the credits.
- Thomas and Percy's Mountain Adventure is out-of-sync. It uses footage from the original UK episode with the correct music and sound, though George Carlin's voiceover remains untouched. This version is also used in Thomas' Christmas Wonderland and other Thomas Adventures.
- Like Thomas' Christmas Wonderland and other Thomas Adventures, the description says that Thomas, Percy and Terence shoveled out villagers just in time for Christmas, but in the US version of the episode that it is referring to, it was Thanksgiving and not Christmas.
