Please note that for Item #1, the change you requested did not work as it seems to have removed the formatting of the post title and such. However, I made the following change which seems to have worked. Can you verify that this should not be a problem.

Changed Lines:

$current_post = do_shortcode($wp_embed->run_shortcode($video));

$current_post = str_replace($match_video[0], “”, $current_post);

To Lines:

//$current_post = do_shortcode($wp_embed->run_shortcode($video));

$current_post = $current_post;

Note: These are lines 121 & 122..

Also, for item #2, your change worked without problem but is there a way to also make it so the post title is not type blockquote? That way it will look like a normal post except for the format type icon on the left..
