There is no season 12. On August 7, season 11 wraps and we loop back to season 4, episode 1 (seasons 1-3 will not be shown). On August 11, when "Here's Lucy" begins airing, "Daddy" begins airing two hours later, still continuing with the long unaired season 4.
Cozi also aired the last few season 4 episodes before starting with season 5. The transfers that Cozi uses are different from the ones on ME-TV and look markedly better. They also have the "Danny Thomas Show" opening restored. The one thing I absolutely hate is that it airs in widescreen...
