The extras seem more substantial than previous DVRAB with every episode having a commentary rather than only some, plus Greg Davies does a commentary on one episode.
The ones with all the 4 laRAB together do tend to ramble on and talk all over the main funny lines without comment which is a bit annoying. They talk allover and don't reference the "I'm gonna f*** your f***ing fanny off you t***" line in series 3.
