On our local PBS station, there is a program called "Manor of Speaking." You can get free tickets to watch DA in a studio audience, and then they discuss the episode in "Manor of Speaking" immediately after. The audience asks questions, and they have a panel of experts that changes every episode, and they always have little tidbits of knowledge to add.
Here is an example of one guest panel last season, from their facebook page:
It's officially the biggest episode yet of Manor of Speaking - Martha Stewart, Lady Carnarvon (of Highclere Castle) & Holland Taylor will be joining Ernie Manouse, Helen Mann, The Professor Robert Patten and Butler Mr. Rogers (@Luke Wrobel) plus The Alley Theatre's Gregory Boyd & CultureMap's Tarra Gaines in this Sunday night's season Finale - immediatel;y following Downton Abbey - only on Ch8 - HoustonPBS
FYI: Highclere Castle is the castle used as Downton Abbey
This is their facebook page, but DO NOT go here if you aren't caught up because there WILL be spoilers:

I get a kick out of seeing how seriously the audience members of Manor of Speaking take the show, you would think they were talking about real people that they know personally! The audience has a broad mix of people. One episode they took a question from an audience member, and it was Joanne Herring, the socialite that was depicted in the movie "Charlie Wilson's War."
