This DVD has only been released in the UK and Australia.
It has not been released in the US yet as a physical DVD, and it is unknown if it ever will be. However, it's available in the US for digital download on iTunes and Amazon Instant Video as a "movie" (which is really just the individual episodes put together on one long video, similar to selecting "Play All" on a DVD). It is also available on the PlayStation Store for PS4, PS3 and PS Vita. 
This DVD was released on Matt Berry's 43rd birthday.
