This how I modify it to accept Custom Post Type (for example : video):

single.php :
related_posts('video');

related-functions.php :
> line 7

function related_posts($posttype = 'post', $a = array(),$echo=true,$reference_ID=false) {
	return yarpp_related(array($posttype),$a,$echo,$reference_ID);
}

magic.php :
> line 283 (maybe the number of the lines are wrong)

// get the related posts from postdata, and also construct the relate_IDs array
$yarpp_related_postdata = get_post_meta($reference_ID,YARPP_POSTMETA_RELATED_KEY,true);

– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –

Here we have to modify how it get the related ID (of posts).
This is how it works :
1) yarpp.php

// update cache on save
add_action(‘save_post’,’yarpp_save_cache’);

->

2) magic.php

function yarpp_save_cache($post_ID,$force=true)

if (yarpp_get_option('cross_relate'))
		$type = array('post','page');
	elseif ($post_type == 'page')
		$type = array('page');
        elseif ($post_type == 'video')
                $type = array('video');
	else
		$type = array('post');

3) magic.php

function yarpp_cache_enforce($type=array(‘post’),$reference_ID,$force=false)
->
$related = $wpdb->get_results(yarpp_sql($type,array(),true,$reference_ID), ARRAY_A);

4) magic.php

function yarpp_sql($type,$args,$giveresults = true,$reference_ID=false,$domain=’website’)

if ($type == array('page') && !$cross_relate)
    $newsql .= " and post_type = 'page'";
  elseif ($type == array('video'))
    $newsql .= " and post_type = 'video'";
  else
    $newsql .= " and post_type = 'post'";

You can improve the script trying to accept multiple Custom Post Type :
related_posts(array(‘video’,’portfolio’,’gallery’));
