I have watched the series on YouTube , Dailymotion , and Disney . But there is one episode that is yet to be found fully. That is the Christmas episode that aired on December 8th of 2008. As of right now there is only one clip of it online on YouTube. This aired on Disney Channel when it was released and once on CBS Toon Disney Saturday line up.

More info on the partially lost episode is provided below. https://disney.fandom.com/wiki/Dick_Daring's_All-Star_Holiday_Stunt_Spectacular_V

"Dick Daring's All-Star Holiday Stunt Spectacular V" is the 41st episode of The Replacements, and the series' Christmas-themed episode.

The Synopsis of the episode : Dick Daring hosts a 1970's-style Christmas variety show, produced, directed and co-starred by Riley Daring. In his opening monologue, the patriarch of the Darings theorizes that Santa Claus is in fact a stuntman. Todd performs his own twisted version of Charles Dickens' A Christmas Carol. Special guests include Carson Palmer, a reluctant Josh Duahmel, and Ed Begley, Jr. who preaches environmentalism. Dustin Dreamlake sings his new hit "Get My Santa On," Buzz Winters tries to read a poem on the show, Agent K tries (and fails) to hide her identity, and Dick performs an elaborate all-star stunt salute to the holidays.
