We've been trying to convince Granada Media to launch a DVD for years; they were the ones who suggested the idea in the first place! But they hardly even bother to respond to requests and petitions about it, so we really can't explain why they won't launch it. Just vague stuff about no one suggesting a viable form to release it in is all we are told. Knightmare is on Challenge on weekday mornings at the moment. Their rights to the series are expiring, but they haven't ruled out renewing them.
