re. getting permissions from the Beeb for releasing material on DVD: this may not be a precisely similar situation but 3 or 4 years ago I was trying hard to get a licence to remaster and release on DVD all of the surviving footage in the BBC archives of the late Jake Thackray. The BBC were very helpful and supportive, particularly since we already knew the library index codes for most of the footage, but the arm which handles the licencing would not budge from the position that they had to charge the same rate whether I was looking for a very limited release to a small group of fans or a world-wide release of a blockbuster. As I recall the rate then was around £1000 per broadcast minute of video footage which blew the project out of the water.
