Redirect more than one custom_post_type

I need help adding redirect code for a 2nd post_type. I’ve successfully added a custom_post_type and it’s being redirected using the following code. My problem is that I can’t add another one for another post type that I also have. When I try it says “function add_new_rules already defined.” (or something similar) Is there a way to combine both redirects into one set of code?

Thanks in advance for any help you can offer.

add_new_rules();
function add_new_rules(){

	global $wp_rewrite;

	$rewrite_rules = $wp_rewrite->generate_rewrite_rules('my_post_type/');
	$rewrite_rules['my_post_type/?$'] = 'index.php?paged=1';

	foreach($rewrite_rules as $regex => $redirect)
	{
		if(strpos($redirect, 'attachment=') === false)
			{
				$redirect .= '&post_type=my_post_type';
			}
		if(0 < preg_match_all('@\$([0-9])@', $redirect, $matches))
			{
				for($i = 0; $i < count($matches[0]); $i++)
				{
					$redirect = str_replace($matches[0][$i], '$matches['.$matches[1][$i].']', $redirect);
				}
			}
		$wp_rewrite->add_rule($regex, $redirect, 'top');
	}

}
add_action("template_redirect",'template_redirect');
function template_redirect()
{
	global $wp;

	$muley_custom_types = array("my_post_type");

	if (in_array($wp->query_vars["post_type"], $muley_custom_types))
	{
		if ( is_robots() ) :
			do_action('do_robots');
			return;
		elseif ( is_feed() ) :
			do_feed();
			return;
		elseif ( is_trackback() ) :
			include( ABSPATH . 'wp-trackback.php' );
			return;
		elseif($wp->query_vars["name"]):
			include(TEMPLATEPATH . "/single-".$wp->query_vars["post_type"].".php");
			die();
		else:
			include(TEMPLATEPATH . "/".$wp->query_vars["post_type"].".php");
			die();
		endif;

	}
