    add_rewrite_tag("%cat_id%", '([^/]*)');
    /*add_rewrite_tag("%video_src%", '([^/]*)');
    add_rewrite_tag("%video_title%", '([^/]*)');*/
     
    // Before And After
   //add_rewrite_rule('services.html', 'index.php?category_name=services', 'top');
   //add_rewrite_rule('services.html', 'index.php??cat=8', 'top');
    $cur_cat_id = get_cat_ID( single_cat_title("",false) );
    $category = &get_category($cur_cat_id);
