It's been discussed on here before. In-case you don't know why it appears to be slower/faster in different display modes, it's actually a trick of the eye. If you play in 4:3, the "players" are running across a small square area. If you play in 16:9, the image is expanded, and so the graphics are expanded. A player has to reach the middle of the screen in the same time that he does on 4:3, but because the image is stretched, it appears that he reaches that point quicker.
Put it like this. Say you play a video on a 4:3 TV of a man running from the very-left to the very-right of the screen, and it lasts for one second. Then you take that same video and you play it on a one-hundred-foot long specially made widescreen TV. It wouldn't take a longer time for him to run that distance, because it's the same video and the video is being stretched to fit. It would still take one second for him to move from the very left to the very right of the screen, which would make it look like he was moving at 100ft-per-second. :mryellow:
