Hi guys. This is Bez from DivX.com. I saw your complaints about our search engine, and wanted to point you at our Search FAQ, which explains how to prevent our crawler from crawling your site.

Also, if you send us a note using our Report a Movie page, we're happy to remove any and all videos on your site from our search index. We do this several times a week.
Thanks.
