if you have mozilla you will see that at both ends of the nav/menu bar there is white space.

 

this is the css i have for the menu

 

#menu {
    width: 800px;
    padding-left: 15px;
    background: url(http://www.sportquadchat.com/images/menu.jpg) bottom left repeat-x;
}
#menu ul
{
    list-style: none;
    padding: 0;
    margin: 0;
}
#menu li
{
    float: left;
}
#menu li a
{
    background: url(http://www.sportquadchat.com/images/menu.jpg) bottom left repeat-x;
    height: 2em;
    line-height: 2em;
    float: left;
    width: 6.4em;
    display: block;
    color: white;
    font-size: 20px;
    text-decoration: none;
    text-align: center;
}
#menu li a
{
    float: none;
}

You have a 5px black border around #maincontainer. The whitespace you are seeing isn't whitespace, it is the border around the container.
