Pb de CSS sous ie

Bonjour,
J'ai un probleme sous ie (toujours lui), les backgrounds des tds ne sont pas bien alignés par conte sous firefox et safari, aucun pb.
Voila mon CSS :
.liens{
background-image:url(http://mlb.niloo.fr/images/barre.jpg);
margin-left: auto;
margin-right: auto;
margin-top: 0px;
width: 178px;
}
.contenu {
position : absolute ;
top : 202px ;
left : 324px ;
width : 550px ;
height : 1250px;
color : red }
.content{
background-image:url(http://mlb.niloo.fr/images/news_17.jpg);
margin-left: auto;
margin-right: auto;
margin-top: 0px;
width: 556px;
vertical-align:top;
}
.dessinc{
background-image:url(http://mlb.niloo.fr/images/dessins_17.jpg);
margin-left: auto;
margin-right: auto;
width: 556px;
}
.aboutc{
background-image:url(http://mlb.niloo.fr/images/about_17.jpg);
margin-left: auto;
margin-right: auto;
width: 556px;
}
.menubg{
background-image:url(http://mlb.niloo.fr/images/barre.jpg);
margin-left: auto;
margin-right: auto;
margin-top: 0px;
width: 178px;
}
