NFS connections fail unless XBMC is run as root

[mk01]

this looks like you are missing the insecure export option on the nfs exports.

insecure means, that server will accept remote connections from ports above 1024. by standard this is not allowed.

the issue is the fact that on unix systems non-root processes cant initialize connections on ports below this. that,s why it works if you are on root.

go to the server and add "insecure" to the export options.
