One thing I noticed about said episode when ITV3 repeated it a couple of years back, for several years (certainly since the switch to 16:9, if not before) the picture quality on the studio work has been noticably worse than the location work, and there's thin black bars down the side that also aren't there on the location work, I assume down to the cameras that were used in the studio, by the time of the episode of Zoe blowing up home farm, that had gone, so presumably they'd replaced the studio cameras. We still have the poorer picture quality on the current ITV3 episodes, so the replacement of the cameras can't have been very long before that episode.
