Tvix 6500, Mede8er MED600X3D and Readynas 104

Has anyone set up any of these players with NFS as I cannot get them to work on NFS with my Readynas RN104. I have turned on NFS on the shared folders on the NAS but have no idea what to put into the respective players so they can see the NAS. I know i have to put in the NAS ip address but its the share name I cant get correct. My NAS is named NAS then the hard drive is named WD_RED_4TB and my movie folder is called Movies. Can someone give me a dummies guide to what the share name should be so the players can connect to the NAS via NFS. They can connect via SMB with no problems but I get stuttering and audio loss on high bitrate rips. The only experience I have with NFS was with Allegro NFS which works fine from the PC with the 2 players.
