Duplicate terms displayed even when using the "Distinct" option in views

Hi Forums,

I have the view below which lists terms in a vocabulary and displays their images using the taxonomy_view module. The problem comes when I post two video pages on a term, it displays the term twice on the result of this view. I dont know how to remove the duplicates and looks like the DISTINCT = YES option does not work.

Any ideas?

$view = new view;
$view->name = 'Video';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
