Hi Jake..
Example post_type as array:
query_posts( array( ‘post_type’ => array(‘post’, ‘movie’) ) );
I lifted the line above directly from WP Codex examples here. (In this example ‘movie’ happens to be a custom post type).
Re the title.. I am using a couple of select plugins but none should be interfering with the title in any way. It appears to me that the blog name ordinarily gets included in all titles by default..? For me, the only pages it wasn’t appearing on were the custom post type archive pages…until I elevated your priority setting.
