When?

I think they fell in love as a very gradual process. I don't know about the change of heart regarding the Manor. I think she wanted to be the sole owner. That's apparently the only reason she married Marton, her first cousin so she'd at least be a part owner.
Actually, Richard was on the verge of proposing several times but something always interrupted him, such as Brabinger coming into the room to announce something or various other interruptions. In the documentary included in the box set it's mentioned that they finally had to do something about getting married as they had kept the audience in suspense for too long.

One thing that occurred to me, having rewatched the Christmas special, was that it was lovely to see Audrey & Richard "post-wedding" - you know, what they were like together, even though they spend most of the episode apart. It was great to see that the fighting was still going on, even though they're obviously still madly in love. The bit near the end where Audrey tells Marjorie about how she doesn't miss the Manor, she misses Richard - that was really an "aww" moment for me. Richard comes first, the Manor is second - hurray.

"Just the one, dear?"

I doubt that the special will be available in the USA, or even released in Region I. You can buy a Region II DVD at:

As for the original topic, I believe that Audrey knew Richard wanted to marry her early in the series, but both knew that it was improper for him to ask unless she made it clear that she wanted him to, since she was old aristocracy and he was nouveau riche. After all, the main focus of this series was the interraction of the various social classes, and what happens when classes traditional lower in stature gain at least a temporary advantage. This is also why it was proper for Audrey to introduce the subject of marraige herself.
