And before the advent of the Aurora and Hedghog, there were the likes of the Domino, Pineapple and Dinosaur - all now extinct (or at least no longer in production).

In addition to using standards converters for instantaneous conversion from 625-line to 405-line signals, some older VHS recorders were able to record and play back 405-line signals, owing to the fact that they recorded a complete frame of video without any cognisance of the frame's internal structure. Later machines perform processing of the signal, such as substituting "drop-outs" from adjactent lines, which wouldn't work with the different structure of 405-line frames.
