I have also been searching for this Drama to be available for many years. I saw the original and only airing of Diana in the 1980's and eagerly awaited the repeats several years later. Unfortunately the repeats have never seemed to come. I was 15 when i saw the original and our family did not own a Video recorder at the time, so I had no chance of recording it. Surely someone knows where the dusty film reels are in the BBC and I feel that a re-airing of this drama, now that Jenny Seagrove has become more famous in Judge John Deed, would offer this masterpiece to a new audience. I would willingly pay to own the series on tape or DVD, but alas this seems impossible. The love story is excellent, watchable many times over and a great favourite of mine. I own the book and have read it over and over, but still long to re-watch the brilliant BBC Drama again.
