Okay. The shows exist, but nobody wants to sit thru programs about planetary moons. They' not popular and they're too specific for general interest programming. It's not "good television".
You'll need to comb through all 47 seasons of PBS's series NOVA and search the episodes that talk about the planets, where the moons get talked about as a side bar. And Professor Alex Filipenko did a series of lectures that hit on the planetary moons.
Those shows are out there- you'll just have to look for them.
