Show only Youtube descriptions in posts

The current youtube addon only embed the video into posts..(its suppose to do this, I know)

Is there any way to modify the code and show the video description instead of embedding the video?

function process_video( $post_data, $ablog, $item ) {

extract($post_data);

if(strpos($item->get_permalink(), 'http://www.youtube.com/watch') !== false ) {
$post_content = $item->get_permalink();

}

return compact('blog_ID', 'post_author', 'post_date', 'post_date_gmt', 'post_content', 'post_title', 'post_category', 'post_status', 'post_type', 'tax_input');

}

Would be looking forward...
