Problem with JWplayer. Video is missing?

Firstly, I am new at using video with wordpress. I have installed the jwplayer plugin and using this bit of code to show the video player on the page.

$video_array = explode("\r\n", stripslashes(extra_option('video_links')) );

            foreach($video_array as $vid){
                if (!empty($vid))
                echo jwplayer_tag_callback("[jwplayer config=\"Homepage Player\" file=\"$vid\"]"); 
            }

Note:

"Homepage Player" is a custom config i made form the jwplayer plugin option page.

Problem: You can see the site here http://photographersinsiouxfallssd.com/ There are four video to show. For the first three the player isn't showing and the last one player is showing but you can only hear sound but no video :(
