I've always been able to stream movies stored on my Windows 7 computer's local hard drive to the Xbox 360 with no problems. A few weeks ago, though, I got a Seagate Dockstar NAS device and moved my movies to it. Ever since then, I can't seem them in the Xbox.

I've tried several different things. When I try to add the mapped drive to the Media Player library, it says that it can't share the files. (I don't have any security on the NAS drive). I've tried creating a symlink to a local drive, but that doesn't help. Neither does adding the UNC path directly.

The Dockstar seems to have its own Xbox share capability, but it doesn't respect my folder structure - it brings over every video file on the drive in a single list, including several hundred home videos that aren't playable on the Xbox.

Is there any way to use Media Player (or the Zune software) to share files stored on a NAS drive? Barring this, is there a lightweight, free server that will allow me to share these files while maintaining my folder structure?
