Well I suppose you might want to do 480i output from 240 lines if your CPU couldn't calculate the game faster than 30 fps... Doesn't really matter though since that isn't the case with any consoles I know of. TVs are so simple (at least conceptually), I'm not sure why there's so much confusion around here regarding them.. Guess it's just something like Ohm's law, lots of people kinda know it
