It will access my Windows box via NFS, so I installed NFS and did that (SMB's not working at all - very annoying). However, it doesn't display the show information nearly as intelligently and completely as XBMC and Boxee Box do, so unless I can find a solution in a few days it's going back. For example, it will download the movie information, but I must enter the movie's folder to display all the information about it (Boxee Box and XBMC both abstract all folder bits and physical location information from the media library / browser). The TV shows I have have no information about the show, and if I turn on the TV Show View, it only shows me one show of the 75 shows total that my media library has.
I'm very, very unimpressed.
