Can I use a Joomla plugin in a template override?

I've made a custom field to hold a video url for my products. I'd like to add simple line like

into the product show file but Joomla doesn't parse the plugin code since it's not in the content area.
Is there a way to do this?

Hi,

You should try like that:

<?php echo JHTML::_('content.prepare','{youtube}'.$this->element->video_url.'{/youtube}'); ?>

Tried that but it just output the tag. Here's my actual code

and here's the ouput

It's building the tag perfectly but not parsing it.

(Spaces added to the php tags so it will show in the forum)

And did you publish the multimedia box plugin ? Looking at the code of the plugin I don't see why that wouldn't work.

Are you able to display it with the same tag code in a joomla article ?

Yes. I use the mbox plugin on another page in the site. I build the tag dynamically there as well. I used that pages output to make sure I had the tag right on this one.

I tried using rokbox instead of mbox and it works. Not sure why mbox won't parse that way but it has to be something with their plugin. I'll see if I can get a response from yoojoomla on it. Thank you for your help.
