I’m extremely lucky to have Arthur’s Big Hit and all the other Arthur DVDs that were released by Sony Wonder from 2006 in my Arthur VHS/DVD collection. Those are the hardest to find for a decent price these days.
Here's my collection: VHS - Arthur's Eyes - Arthur's Lost Library Book - Arthur's New Puppy - Arthur Makes the Team - Arthur: The Music Video - Arthur's Treasure Hunt - Arthur's Scary Stories - Arthur's Perfect Christmas - Arthur's Celebration - Arthur Family Feature - Parents Are From Pluto - Postcards from Buster: Buster's Got the Beat DVD - Arthur's Big Hit - Arthur's Family Fun (Our Time release, not to be confused with the completely separate DVD from Sony Wonder with the same title).
Arthur The Wrecker aired on December 9, 1996. Arthur Vs The Piano aired on November 10, 1997. Arthur’s TV Free Week aired on November 3, 1997. Night Fright aired on November 3, 1997. DW Rides Again aired on January 27, 1997. Arthur’s Cousin Catastrophe aired on November 4, 1996.
My guess as to why the "Arthur's Big Hit" DVD is so rare is because the episode was so bad, and often considered the absolute worst episode of the entire show, that even the writers themselves were ashamed. I mean in the UK, they had the Complete Season 4 DVD and every episode was there, except for "Arthur's Big Hit".
Well I would assume around that time said DVD came out in June 2006 was that Sony Wonder was concluding its Arthur license and I would think there weren't very many copies printed for Arthur's Big Hit DVD and some other Sony Wonder Arthur DVD's released around 2003-2006 before WGBH Boston Video and PBS Distribution would begin releasing Arthur DVD's of their own, and some of the last Arthur VHS and DVD ever to be released by Sony Wonder including Arthur's Big Hit, You Are Arthur and Arthur's Club Rules are incredibly rare and expensive to find today.
