@ Steve: I got EXACTLY the same issue you have, either a blank menu with sound or a black screen also with sound, depends on your type of dune installation, when deleting the intro vids from your dune folder, you only get the black screen. The strange thing is that it works fine on my vista 64 installation, which runs on the same pc my windows 7 64 runs on. so it only works with vista and not with windows 7 for me, regardless of the hardware, which is very strange. I even contacted gruntlord about this issue, since many others are experiencing this too, but he couldnt find a solution for it. I hope someone will find a solution eventually.
