I'm using freenas on one of my old comps for a NAS.
Have installed Ubuntu 12.10, XBMC and ps3 media server onto another computer in the lounge for a media pc.
I managed to point XBMC to the NAS but can not find away to get there in PS3 media server.
The idea is to use XBMC to play stuff on the TV and use ps3mediaserver to stream to xboxs around the house.
I havent used ubuntu much before this.
