This guide is showing its age, but it should help you figure out how to download videos from this site.http://www.animemusicvideos.org/guides/ ... r/down.htm
Unfortunately, the video you're looking for (this one, if I'm not mistaken
) doesn't have any download links. The general advice we give for this is to see who left an opinion on the video, and try to track them down to ask if they have a copy. However, the two people who left opinions on that video haven't logged on in years.
Sorry to say, but I think you're out of luck on finding a copy of that video.
