Seriously Simple Podcasting category link

Hi, I have this plugin for podcasting and would like to link the podcasts to a category rather than a series, for the sake of front page design. The great guys at the plugin have provided the code to paste into functions.php –

add_action( ‘init’, ‘ssp_add_categories_to_podcast’ );
function ssp_add_categories_to_podcast () {
register_taxonomy_for_object_type( ‘category’, ‘podcast’ );
}

However, within the category on my site, only posts show up and not podcasts even though they are both marked under a given category.

I hope I’m not missing anything obvious.

Thanks for any help

Chris
