Akradon on "Custom Title Categories not visible?"

Hey guys, I know pretty much nothing about PHP and I've used internet tutorials and copy n pasting to make a 'video' option for my site. I've tried to make it have their own categories, which I can select and choose when creating a post. But they aren't visible on the post screen or on the website itself?

function my_custom_post_videos() {
	$labels = array(
		'name'               => _x( 'videos', 'post type general name' ),
		'singular_name'      => _x( 'video', 'post type singular name' ),
		'add_new'            => _x( 'Add New', 'video' ),
		'add_new_item'       => __( 'Add New Video' ),
		'edit_item'          => __( 'Edit Video' ),
		'new_item'           => __( 'New Video' ),
		'all_items'          => __( 'All Video' ),
		'view_item'          => __( 'View Video' ),
		'search_items'       => __( 'Search Video' ),
		'not_found'          => __( 'No video found' ),
		'not_found_in_trash' => __( 'No videos found in the Trash' ),
		'parent_item_colon'  => '',
		'menu_name'          => 'Videos'
	);
	$args = array(
		'labels'        => $labels,
		'description'   => 'All the videos from Geeking It Up A Notch',
		'public'        => true,
		'menu_position' => 5,
		'supports'      => array( 'title', 'editor', 'thumbnail', 'excerpt', 'comments' ),
		'has_archive'   => true,
	);
	register_post_type( 'videos', $args );
}
add_action( 'init', 'my_custom_post_videos' );

function my_taxonomies_videos() {
	$labels = array(
		'name'              => _x( 'Videos Categories'),
		'singular_name'     => _x( 'Video Category', 'taxonomy singular name' ),
		'search_items'      => __( 'Search video Categories' ),
		'all_items'         => __( 'All video Categories' ),
		'parent_item'       => __( 'Parent video Category' ),
		'parent_item_colon' => __( 'Parent video Category:' ),
		'edit_item'         => __( 'Edit video Category' ),
		'update_item'       => __( 'Update video Category' ),
		'add_new_item'      => __( 'Add New video Category' ),
		'new_item_name'     => __( 'New video Category' ),
		'menu_name'         => __( 'Video Categories' ),
	);
	$args = array(
		'labels' => $labels,
		'hierarchical' => true,	

);
	register_taxonomy( 'videos_category', 'videos', $args );
}
add_action( 'init', 'my_taxonomies_videos', 0 );

That's the code I'm using. If someone could help me I'd be very grateful.
