Do these movies play for you?

When Fusker sends referral then my htaccess blocks it no problem but often referral info from Fusker is blocked and then my images or mpegs are served up since I have no referral allowed in my htaccess.

Then you can't use the HTTP_REFERER to validate if you are being hotlinked or not. You got 2 options :
1 ) use cookies ( js or other server side script )
2 ) get a hotlink protection script

If it is not for galleries, you can rename the files through some php cron job.
