There was a thread on the Flypast forum a few months ago which sparked off some DVD copies of this magnificent film. If any of you also frequent that forum I would suggest asking around there. I got one of the copies and am well chuffed with it. Unable to produce more though (don't have a DVD burner!)
To avoid setting off a mile-long list of requests for this I won't post the details of where to find this thread here. PM me if you want more hints.
