- This DVD is a combination of Thomas' Christmas Wonderland and Thomas' Snowy Surprise as they have the same episode, songs and bonus features.
- This was the last US DVD to feature the nameboard sequences, as well as the last to use the 2003 Anchor Bay Entertainment logo.
- It was also Anchor Bay's last Thomas DVD to feature any interactive games.
- The trailer uses the Starz Home Entertainment logo while the actual release has the Anchor Bay Entertainment logo
- Since this release is a compilation of Thomas' Christmas Wonderland and other Thomas Adventures and Thomas' Snowy Surprise and Other Adventures, the title card from the former is used.
- 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 shovelled 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.
- The End Credits at the end are played twice.
