Theming Node type

To theme the layout for a particular content type you need to create a file called node-yournodetype.tpl.php. So to theme the blog node type it would be node-blog.tpl.php. The only mistake I see that you made was using an underscore instead of a hyphen.

Getting the view to only show a particular node type just requires adding a filter and using the node type option. Once you create a view for a particular content type having that view show up when a particular content type is loaded (such as the video example) would require loading the view from within the node-video.tpl.php content type by the means of php. To understand how to insert the view into the tpl see this tutorial http://www.pixelclever.com/how-programmatically-insert-a-view-drupal-6 .

Thanks Aaron, that has made things much clearer and the tutorial very helpful. I am not sure why I did not pick up that was the way it has to be done. So I am presuming if you insert a view then the theming is done on the view?

I followed the instructions and used your php snippet to relate the view to the video node type, however, in my case the same video shows each time (the first in the gallery), however the title and the comments relate to the video thumbnail clicked? What am I missing here? Thanks

Ok worked it out.
Added the argument Node: Nid to specify a single node and then send the argument so the code that inserts the view looks like this.
<?php
$view_args = array( $node->nid );
$display_id = 'Page_1';
$view = views_get_view('viewname');
if (!empty($view)) {
print $view->execute_display($display_id , $view_args);
}
?>

array( $node->nid ); - ???
