I just saw a commercial for the "Oprah meets her neighbors" episode taped last May (2007). It is going to be shown on Wednesday.
Our neighbors down the hall had a party that Oprah came to and was featured on that episode. The second half of the show features the balcony renovations in the building facing her studios. Our unit has a tiny enclosed balcony so it was not part of that. But I was at the party, it was amazing, you can read about it here.
