When I ran 640x480 in component mode, the edges were cropped off. After doing a search, I found this was very common. If you use 640x432, it eliminates the cropping but a lot of video cards don't seem to be able to do this without Powerstrip. Using MaLa as my front end, I input 640x432 and the ATI is able to do it with no helper app. Windows toolbar is cropped while booting (640x480), but once in the front end, everything is perfect.
