Alright, You can just hook into the filter pre_get_posts and check is_admin.
Put this in your theme or plugin:
function wpse_81939_post_types_admin_order( $wp_query ) {
if (is_admin()) {
// Get the post type from the query
$post_type = $wp_query->query['post_type'];
if ( $post_type == 'Videos') {
$wp_query->set('orderby', 'date');
$wp_query->set('order', 'DESC');
}
}
}
add_filter('pre_get_posts', 'wpse_81939_post_types_admin_order');
I also would shange the post_type “Videos” to lowercase like “video”.
