For people who haven't donated, there's a donation page that you have to click through after you click on LOCAL, and before you can download.
You don't have to donate, though donations are always appreciated. At the bottom of the donation page you should see 3 buttons. 2 say "pledge" and 1 says "proceed", click on the proceed button and you'll be taken to the real download page. The AMV should start downloading about 5 seconds later.
Yeah, the system is a bit screwy...but it's what we have.
