Little Blue Box (1978). A self-described "horny but faithful" husband (John Leslie), disappointed by his wife's (Jennifer Welles) frigidity, tries to spice things up with the help of an adult home-movie system sold to him by the lovely Miss Azure and featuring the mysterious Channel 69.
Several well-staged sex scenes, including one with the lovely Leslie Bovee, fleck this relic of the golden age of adult flicks. It's got an endearingly corny sense of humor, too. Leslie's snacking scene when he finally unlocks the secret of Channel 69 is a hoot.
