How To Setup NitroTV to network with my MacPro using NFS

Is there a way to configure NitroTV through the Network settings to set and stream video from my internal drives on my MacPro using NFS? I have NFS Manager on my MacPro and have already setup NFS Server definitions with my internal drives. I followed the prior thread about setting up a networked Drobo, and tried to set up a NFS mount point without success. I also tried a SMB mount point definition without success (the AppleTV only reboots every time I try to mount one on my MacPro’s internal drives).

Does anyone have more specific information on how to set up NitroTV’s network setting to work with an NFS server?
