Here is what i have in syndicator, the php code i obtained from your tutorial on gfy:

Custom Fields:

screen_url::screen_url
screen::screen
clip_url::clip_url
flv::flv

PHP Code <?php .. ?>:

// put the site link to paysite into the 'paysite_url' custom field according to Free WordPress Tube doc
$post ['custom_fields'] ['sponsorlink'] = $post ['custom_fields'] ['paysite_url'] = 'Login to see this link;;
$post ['custom_fields'] ['join_now']='Login to see this link;;
$post ['custom_fields'] ['paysite_title']='Bootylicious Mag';
// “sponsor” field
$post ['custom_fields'] ['sponsor'] = '<strong>Bootylicious Mag</strong> – The online magazine dedicated to big ass booty! And if “ass” is the subject you know the sistas will represent! Features some well black pornstars and quite a few first timer new faces. They stingy with the free previews, but make up for with the sexiest big booty black and latina girls on the internet.';
// format clip's duration as mm:ss
$post ['custom_fields'] ['duration'] = date ( 'i:s', $post ['custom_fields'] ['duration'] );
// fake random time from 0:20:00 to 2:00:00
$post ['custom_fields'] ['time'] = date ( 'i:s', rand ( 1800,3600) );
// generate random tags. Don't forget to replace tag1, tag2 etc with the prefered tag names. Also don't forget to enable “Create tags from category names” option on the feed settings page
$post ['categories'] [] = array_rand ( array (“tag1”, “tag2”, “tag3”, “tag4” ) );
// create an URL of thumb from it's path and file name
$screen = $post ['custom_fields'] ['screen'];
if (is_array ( $screen )) {
    $post ['custom_fields'] ['thumb'] = $post ['custom_fields'] ['screen_url'] . $screen [rand ( 0, count ( $screen ) – 1 )];
} else {
    $post ['custom_fields'] ['thumb'] = $post ['custom_fields'] ['screen_url'] . $screen;
}
// uncomment the line below to store thumbnails on your server
cseo_store_image ('thumb', $post ['post_title']);
// since FLV videos have no unique GUID's let's use their URL's as post GUID's  
$post ['custom_fields'] ['hostedflv'] = $post ['guid'] = $post ['custom_fields'] ['clip_url'] . $post ['custom_fields'] ['flv'];
// now let's delete all useless custom fields
unset ( $post ['custom_fields'] ['screen_url'] );
unset ( $post ['custom_fields'] ['screen'] );
unset ( $post ['custom_fields'] ['clip_url'] );
unset ( $post ['custom_fields'] ['flv'] );
