In the details of an AMV there are 4 types of download:
Direct - the best thing

you can right-click the link and "Save target as..."
Indirect - the link on the font leads you to a site where you can
possibly download the AMV
Local - a good thing, but your first 14 days ( i call it "14-days-come-to-life-period" ) you cannot download from local drives.
No - the worst thing...

this AMV you cannot download because it's not uploaded anywhere....
