oembed fails in custom field

We use <?php print_custom_field('introductie:do_shortcode'); ?> to show an wysiwyg field. If we place a youtube video and rely on oEmbed this works in the backend, not the frontend. As per https://code.google.com/p/wordpress-custom-content-type-manager/wiki/do_shortcode_OutputFilter we’d expect this to work, however oEmbed maybe different from shortcode. Current result is the youtube url gets printed in the output. Please advise, thanks.
