custom post categories

I have added custom posts 'Webcasts' to my site, displaying only the first one on the homepage, code below:

<?php $num_posts = ( is_front_page() ) ? 1 : -1; 

$args = array(
'post_type' => 'webcasts', 
'posts_per_page' => $num_posts
);

$query = new WP_Query( $args );

?>

I have created 3 categories for this post type (next webcast, previous webcast, and upcoming webcasts). On this page, I only want to display one of these categories, how do I do this??

In case this helps anyone else I have figured out the problem, correct code is:

$args = array( 'post_type' => 'meetings', 'category_name' => 'next-meeting', );

So happy right now!!! :-)

This may be of some use to you: https://css-tricks.com/snippets/wordpress/run-loop-on-posts-of-specific-category/

$args = 'cat=5'; // ID of the category
$query = new WP_Query( $args );

ok, I've changed it to this but now it won't display any posts... ?

$num_posts = ( is_front_page() ) ? 1 : -1; 

                $args = array(
                    'post_type' => 'webcasts', 
                    'posts_per_page' => $num_posts
                );
                $args = 'cat=next-webcast'; 
                $query = new WP_Query( $args );

I've also tried this which seems like it should work, but it just displays the first post, not the specific category :/

$args = array( 'post_type' => 'webcasts', 'cat' => 'next-webcast', 'posts_per_page' => $num_posts );
