.........

    require_once 'Zend/Loader.php';
    Zend_Loader::loadClass('Zend_Gdata_YouTube');

    $yt = new Zend_Gdata_YouTube();
    $query = $yt->newVideoQuery();
    $query->setQuery($searchTerm);
    $query->setStartIndex($startIndex);
    $query->setMaxResults($maxResults);

    $feed = $yt->getVideoFeed($query);

    echo '<pre>';
    print_r($yt);

Instead of $yt, see what you have got in $feed eg:

    echo '<pre>';
    print_r($feed);

has returned the object...

This is because you are using print_r on object eg:

$yt = new Zend_Gdata_YouTube();
