J'ai fait quelques modifs et dépoussiérages.

Essayez pour voir.

#header {
	margin: 0 auto;

/* Logo */

#logo {
	height: 65px;
	color: #FFFFFF;
    text-shadow:  5px 5px 7px #555;
    position: absolute;
    top:20px;
	left:20px;
}
#slideshow {
        width:980px;
        height:150px;
        border-radius: 10px 10px 0px 0px;
        box-shadow:  5px 0px 7px #555;
        background-color:#06C
}

<div id="header">
    <div id="slideshow"> {Showtime show='1'} </div>
    <div id="logo">
      <h1>{sitename}</h1>
    </div>
    <div id="search"> {search} </div>
  </div>


Note: border n'a plus besoin d'être préfixé.

Bon courage Smiley smile
J'imagine que ce n'est pas facile sans l'accès aux images... J'ai essayé les modifs mais ça ne marche pas, les blocs se décalent vers le haut et vers le bas et les coins ne sont pas plus arrondis.

Merci pour le temps que vous avez passé à m'aider.

Smiley smile
En tout cas le code que je vous ai donné (enlever le left:20px du logo) est valide et corrige des erreurs de celui que vous aviez posté.

Attention j'ai déplacé la div slideshow dans le html.

éventuellement donnez les tailles des images. Smiley cligne
