Here's The New Magic Roundabout video released by Polygram Video in 1993. All the episodes on this tape are narrated by Nigel Planer of the Young Ones fame and they were originally broadcast on Channel 4 in 1992.
It always confused me why the description on the back of the video says the programme included 24 TV episodes when the video itself only has 20 episodes.
Anyway, Enjoy :)
