Hi, this is my .htaccess file

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://www.blackmoont.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://blackmoont.com/.*$ [NC]
RewriteRule .*\.(wma|wmv)$ http://www.blackmoont.com/forum/index.php [R]

And i want to protect my movie , music .i'v install mod_rewrite in my serevr , upload that .htaccess to public_html . But it look like a .htaccess file doesnt work . Check this one and u will know :
http://www.blackmoont.com/mbox/blackmoont/tambiet.wmv

Anybody got this problem before ?

I clicked the link, and I was redirected the forum. Which is what that Rewrite rule is suppose to do.
