Some how my .htaccess file got deleted (it wasn't me who done it) and took down my entire site. Anyway tech support replaced it with one contain the entries below. This restored the entire site but I have one remaining issue. When entering the site from a bookmark or by entering the url, mitek-automation.com, in the browser the background video doesn't play. A click on the Home menu item refreshes the page and the video plays. Any ideas?

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

[edit]
This only happens with Chrome. Apparently now prevent autoplay of video
