Much of the media involving the Max Headroom character (in 1985-88, roughly) has never been compartmentalized into proper rereleases and this isn't that surprising. While the original TV spot and later episodic show are intact (at least they have physical releases, though they've been out of print for a while) but there's other material where he hosted runs of music video's, sometimes comically interacting with them, and he even had a talk show where he would converse with celebrities. Much of this would have legal difficulties for rerelease no doubt and its unlikely there'd be an attempt unless they thought it would sell. These productions have been found fragmentally around the net but I've had difficulty even getting a complete list as far as their content.
