You are aware that a DSLR like the xsi is not like a point and shoot where you take all of the pictures using the LCD, right? Live view is more for tripod stuff where you can set up, zoom in up to 10x to check focus, and then take the shot. It doesnt quite work like a display on the point and shoot where you are using the lcd all the time. Most of the time you are using the viewfinder on the dslr.
