Problem solved, I was first led to believe that the div needed to be fixed was called monoslideshow, but nope it was just slideshow. Added the following code in the custom css part of my theme and it was fixed.
div.slideshow {
width: auto;
border: 0px;
margin: 0 auto;
}
object.slideshow {
padding:0;
border:2px #ffffff solid;
display: block;
margin-left: auto;
margin-right: auto;
}
