SMB v2 by default requires full user credentials, meaning name and a password. It is best to use the "Add a network location..." option when creating a video/music source. No idea if SMB v1 or v2 is used ni MacOS X.

NFS is a different animal from SMB, I don't know if MacOS X has default support for it, or that you even installed an NFS server already.
