Question Author
I was annoyed that my copy of the Christmas Special Radio Times had only recently been taken for recycling and I couldn't see 'at a glance' which programmes the BBC had shown on Boxing Day. However the online Radio Times TV listings allowed me to find a likely candidate (I've never watched any of the programmes in the series), which was set in the right part of the country, but even then the programme details don't mention the Jacobean house. I'm not happy until all the pieces of the puzzle have fallen into place, so I had to use iPlayer to set my mind at rest.
