Hide a page title on a certain page view.

views_hide_page_title.module

<?php
/**
 * @file
 * Hide the page title on a page view snippet.
 */

/**
 * Implements template_process_page().
 *
 * Removes the regular page title from news pages.
 */
function via_news_process_page(&$variables) {
  // Only hide the title on the view index page.
  $view = views_get_page_view();
  if ($view && $view->name == 'news' && $view->current_display == 'page_1') {
   $variables['title'] = NULL;
  }
}

I set the title to NULL instead of using unset to prevent undefined variable warnings from the system page.tpl.php.

Note that you can also use hook_page_build.
