Several episodes that have not been released in the United States on DVD have been released in other countries.
"Wednesday Is Missing, the only episode of The New Scooby-Doo Movies still unreleased in the US, has been released on the Scooby-Doo Meets the Addams Family VHS in Australia by Worldvision, as well as on the Scooby-Doo and the Three Stooges & Scooby-Doo and the Addams Family VHS in the UK by Lollipop.
The Scooby-Doo and the Werewolves DVD was released only in Europe, and included "Where's the Werewolf?" from The Scooby & Scrappy-Doo Puppy Hour. It's unknown why this was the only villain compilation DVD never released in the US, when all the others were (i.e. Scooby-Doo and the Pirates, Scooby-Doo and the Ghosts, Scooby-Doo and the Skeletons, etc.).
"Scoobygeist," "The Quagmire Quake Caper," "Scooby the Barbarian" and "No Sharking Zone" from The New Scooby and Scrappy-Doo Show were released on 2019's Scooby-Doo: 50 Cartoon Collection DVD in the UK exclusively, replacing "The Chiller Diller Movie Thriller" on the US version.
