Despite several promises of a release from 2 Entertain, the planned release has fallen through several times, and despite assurances that a release is still coming, nothing has emerged or looks likely to.
The best bet for fans of the show, is a trader on www.ioffer.com (http://www.ioffer.com/i/141626175?from_buyer=1) who is selling series 1 & 2 on a DVD, recorded from the TV. It's good quality but bare bones presentation.
