According to the Finnish Wikipedia, Minimax did briefly exist in Germany, Italy, and Portugal. Darth Man also said that his friend watched a British version of the channel as well (his friend lives in Bournemouth).
Oh yeah, I just now noticed the Inspector Gadget promo that VideoTino uploaded was fake, as you said.
I talked to Darth Man, and he said Minimax continued to use the 1994 logo in the UK even after Spain switched to the newer logo from 1995 (the reason I said 1995 is because I found a magazine from Canal Satélite dating back to that year with the newer Minimax logo on it).
