Warnings of flashing images into TV programmes/news items

Just Posted this in the election thread but it's relevant here too ....

[quote:0224268243]Interesting inserted ticker style warning on the BBC Parliament Election 74 re-run today 'This programme contains strobing throughout'. Presumably to cover the synching issue, or possibly the all too apparant flaws in the VT of the material.[/quote:0224268243]

This kinda reminds me of the Porygon incident in Pokemon, when hundreds of Japanese children had seizures after a scene that flashed red and blue.
