All Series was repeated later in the year in a revised schedule (described as "Reversions") which combined and re-edited two episodes of the original broadcasts to create a series of 1-hour episodes; as all series consisted of fifteen 30-minute episodes, the "Brooklyn to Montauk" (SE01) episode was revised as an extended version that included additional content not seen in the original broadcast schedule. The Series 1 DVD contains only the original fifteen episodes.
