At the bottom in the cuts section it has stated:
***This is for the "The Ultimate Edition – Remastered boxset" containing all Blackadder titles, rather than just the Blackadder's Christmas Carol (1988) title individually (which is similarly affected also anyway).R2 Ultimate Edition United Kingdom- 2 Entertain Video/BBC - Remastered - Yes, a line edited from previous video and some DVD versions still remains cut (3:23-3:24):
Baldrick: "Nah, they loved it."
The rest of the line is cut: "They want us to do another one at Easter. They want to see us nail up the dog."
However for each individual series of Blackadder listing pages:

At the bottom in the cuts section for each, they all say the "The Ultimate Edition – Remastered boxset, Blackadder's Christmas Carol (1988)" is uncut.
As far as I can tell the "The Ultimate Edition – Remastered boxset" is the same listing across each of these link page listings above. So unless i'm misunderstanding something somewhere, it looks like "Blackadder's Christmas Carol (1988)" contains the same cut line in all released DVD versions (individually or with other Blackadder titles in a large boxset). So I think the 4 links pages above need to be updated to include this information.
