Change media template for single product

Question

I am trying to update the media template via XML in Magento. Somehow my method is not working:

First I included <?php var_dump($this->getNameInLayout()); ?>in the template to get the correct block name. In this case the output is: "product.info.media"

Second step is to updated the product design via manage products > Product > Design > Custom Layout Update. Here I try to update the xml for this single product:

<reference name="product.info.media">
    <action method="setTemplate"><name>ecommerceteam/cloud-zoom/catalog/product/view/media-venst.phtml</name></action>
</reference>

This is not working.

Update: This is what happens in the catalog.xml

    <reference name="content">
        <block type="catalog/product_view" name="product.info" template="catalog/product/view.phtml">
            <block type="catalog/product_view_media" name="product.info.media" as="media" template="catalog/product/view/media.phtml"/>

Update:

I was not able to update a child block via the product xml layout. I resorted to switching the theme.

You can update for example with this:

<reference name="content">
<block type="cms/block" name="your_name">
    <action method="setBlockId"><block_id>your_blockid</block_id></action>
</block>
</reference>

If you want to put a block in your template. Or you can update with a .phtml from for example from your template folder:

<reference name="content">
<block type="core/template" name="your_name" as="your_page"  template="page/html/your.phtml" >
</block>
</reference>
