EDIT: as for FZ's question, i don't know. I've messed around with the apsect ratio settings on my ps2 while hooked up to a 4:3 tv & i've noticed it doesn't always do what i'd expect when it's put on the "incorrect" setting. Don't know why though. I've never had any trouble getting it to display properly on 4:3 or 16:9 tvs. so i've never really cared. Oh, & just FYI, i had one of the launch models for a long timel. It was fried by lightning 6 months ago & i've since replaced it with one of the slim units. Both performed identically.
