OK that is good to know that it doesn't seem to be a path or
permissions problem. Also I thought it maybe some database problem but
if it is getting the file name from the database properly then that
isn't likely the problem. Any suggestions on how to use a debugger or
some other way to look at some of the variables in the php. Here is
the relevent code:

 if ($this->cover_file != 'No Cover' && file_exists($this->cover_fil\
e) ) {
            $this->cover_url = 'data/video_covers/'.substr($this->cover_fil\
e, strlen(setting('VideoArtworkDir', hostname)));
            list($width, $height) = getimagesize($this->cover_file);
            $wscale = video_img_width / $width;
            $hscale = video_img_height / $height;
