Has anyone successfully downloaded from FilePost using DS? If so, what's the secret?

I see a link, but DS sees this as a 0 length file; in FP, there is a "High Speed Download" button which has right-click disabled. If I look at the page source, the button has an (insanely long) URL, which if I cut/paste into a download job, DS can then download.

But is there any way of getting at this directly?
