drawRoundRect help

In drawing a rounded rectangle using the drawRoundRect method is there anyway to smooth out the corner. In my example the corners look like crap.


var rect:MovieClip = new MovieClip();
var color:Number = Number("0x"+listColor);
rect.graphics.beginFill(color);
rect.graphics.lineStyle(1, 0x000000);            
rect.graphics.drawRoundRect(0,0,w,h,5);
rect.graphics.endFill();
