I am sorry if this has been asked before,but I'm new to this site. I remember at around the time of the original transmission of the Doctor Who story The Sea Devils, a schools TV programme was transmitted 2 or 3 times which went behind the scenes of this story. It was particularly interesting at the time,because of the huge amount of power cuts that affected the story. What I want to know is if this exists & could it be put to use in a future DVD release if it is in good enough quality. Thanks.
