It's a good series - I wrote to the BBC a few months ago to ask if they were bringing it out on DVD but they didn't know! I've just found the the 'Regency'one on youtube: http://www.youtube.com/watch?v=J1w-6aLlATQ&feature=related
there may be more episodes on youtube, too (god, I love youtube!) - the Elizabethan one had some great costumes...I love the episodes were they have to eat boiled cow head and other horrors.
