All of the mentioned shows did appear on DVD in due course, except one.

Target, tooted as the BBC's answer to The Sweeney, was after its initial airings apparently only ever seen as one episode on a BBC Video, and was (it says here) last seen on the Galaxy Channel on BSB before the merger, and the show has never been seen or mentioned again since.
