Although the series was originally broadcast in Spain in 4:3 standard PAL definition in its first five seasons, the whole series was originally recorded in 16:9 1080p. The original 1080p versions of the first seasons remain unseen in Spanish national TV though, and later re-broadcasts of these seasons are still done in 4:3.

It was however possible to see the 16:9 versions of these seasons on Antena3 Televisión's internet page. It could be seen then that these episodes had never originally been intended to be broadcast on 16:9, as cameras and crew equipment were clearly visible in some scenes in the area of the screen that later was cropped out.
