Not sure if it's the best way to do this, but you can try the following for Drupal 7::
function MODULENAME_preprocess_views_view(&$vars) {
if ($vars['view']->name == 'VIEWNAME') {
$vars['rows']= "<div class='wrapper-class'>".$vars['rows']."</div>";
} } This will wrap contents just below the "view-content" class
