Final Episode missing from Season 2 DVD release
Does anyone know why the last episode(nine) is not included on the season 2 DVDs? I have the first three seasons on dvd and on s1 and s3 there were 3 discs per season, with 3 episodes on each disc, but with season 2, the final 3rd dvd only has 2 episodes (episode 7 and 8).
I thought that maybe s2 only had 8 episodes, but after checking I realised it had 9 episodes just like the others. Then I thought that maybe I was missing a fourth disc (that possibly the final episode was double-sized or something and wouldn't fit on the third disc), but no, that was definitely the last dvd in the set.
Also, according to the episode guides, Cliff Richard was supposed to be on episode 2 (of season 2), but after watching the dvd of that episode he wasn't on it.
