Changing the default posts page name

Hello,

Every time I set a default page for the blog-posts (readings: set page for the posts), it changes that pages title, and replaces it with “Latest News” in the centre.

I’m trying to change that, so far.. unsuccessfully. I’ve tried a few things, like this code i found, but it does’t work:

add_filter('avf_title_args', 'fix_single_post_title', 10, 2);
function fix_single_post_title($args,$id)
{
if ( $args['title'] == 'Latest News' )
{
$args['title'] = 'New Name Here';
}

return $args;
}

Of course, it also would be nice to not have it centred, but rather aligned left, but can’t figure out where.

I’d welcome some help please! Thanks much ??
