Yes I understand you now.
Well I think that the custom fields are required for WP-PostRatings to work correctly, I may be wrong but if this is the case then you must change your code to just retrieve the custom fields you want.
So at the start of the loop we have define all the custom fields you want to show
<?php if (have_posts()) : while (have_posts()) : the_post();
$custm1 = get_post_meta($post->ID, 'custm1', $single = true);
$custm2 = get_post_meta($post->ID, 'custm2', $single = true);
$custm3 = get_post_meta($post->ID, 'custm3', $single = true);
$custm4 = get_post_meta($post->ID, 'custm4', $single = true);
?>
All you do here is change the names of custm1-4 to the exact name of your custom field key..
Then you just display them wherever later on in the template like this:
<?php echo $custm1; ?>
Where custm1 is the name of your Custom Field Key. This will then output the value for this key for the post in question.
Sorry if you are already doing this,
