Unable to write to nfs share

[geekyhawkes]

I am unable to write to my MCE hyrbid shares when i mount them from any ubuntu machine in my house and am not sure why. 

This is the line from my /etc/fstab


# mce Home directory nfs mount
192.168.80.1:/home /media/mcehome nfs rw,hard,intr 0 0


The drive mounts fine and i can explore around, but i am unable to create any folders (and hence add any files i want to my media center).  I went the route of nfs after having problems with samba not mounting the shares from my mce machine (and due to the speed increase under linux of using nfs).

Any ideas?
