I find this quite misleading ... I do not see anything under Download that would allow me to specify which movie I want to download.Sounds like you may be trying to play it through the AnyStream view of the Amazon site instead of Downloading through the AnyStream Download button

I get this message permanently if I want to playback those trailers, but downloading movies always worked flawless, I cant playback them, but I guess this is correct for trailers and for movies too.
