are you sure? Your links show up as broken for me. If you have the images cached, they will show up, i.e. you looked at it, put in the rules, tried again -- you might need to clear the cache. Also, if you send an empty referrer, the image will show up as per your rules.
As a side note, the 1.2.3.4 is supposed to represent your IP address.
Code:
RewriteEngine on
RewriteOptions inherit
RewriteCond %{HTTP_REFERER} !^$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(.*@)?([a-z0-9-]+\.)*thefetishfiles\.net(:[0-9]+)?(/.*)?$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(.*@)?209\.16\.200\.208(:[0-9]+)?(/.*)?$
RewriteRule .*\.(asf|mpg|mpeg|wmv|avi|rm|gif|jpeg|jpg|zip)$ - [NC,F,L]

That's all you should need -- you've got two rulesets in there with one condition. Also, I added a / to the end of your error redirects just to save 1 301 redirect when the person is redirected.
Give that a try, it should do the trick.
