Having had dinner with Arthur, I can say he is a fine chap. I'm sure he has a social media presence, find him and get through to him, and ask him how you can get copies. I met him this spring just before the series was aired, and I wish I could have said to him how superb all episodes were. Don't miss it. Such a shame these programs get lost to history.
Virgin don't allow you to rip DVDs off their boxes- it's not possible.
