WDTV Live with D-Link DNS-323 not connecting

Hi

I just bought a WDTV Live for a new TV in the lounge room. I can’t for the life of me get it to connect to my NAS (D-Link DNS-323) to play media.

If I go into files, music, videos, or photos and choose “media server” under “content source” it shows “NAS” but if I select anything I get the message “there is no media in the current folder”. 

If under “content source” I choose “network share” > “windows shares” then NAS does not appear - just my laptop on the network…

Can someone please help me trouble shoot this? I’m using a wired network.

Thanks

Just changed the workgroup name and it all started working… YAY! Now shows as a windows share
