As far as I can ascertain the only "censorship" issue concerns the Wine, Women and War 2-part pilot. According to the BBFC website, the episode was cut by 16 seconds by the Distributor before being submitted on September 5, 2005. To quote the BBFC: "The Distributor chose to cut sight of a double ear clap to achieve the PG category, on the grounds of imitability."
I scoured both parts of Wine, Women and War and this scene is missing from our version as well. Also, the combined total running time of both episodes for the Region 2 (UK) release is 93:56, which is identical to our own. I can only assume that Universal sourced the Region 2 (UK) Distributor-imposed, censored version for our Region 4 release.
The first season has yet to see the light of day on DVD in the United States. However, according to feedback at Amazon.com, when the first season hits the shelves it will not contain the three, 2-part pilot episodes. When Season 1 gets a US DVD release, I'll update my review accordingly.
