Desktop system fails to show and play files from NAS

[Kenneth Hatteland]

I have a desktop with 10.0 RC2 installed. On the network I have a WD 
Mybook live 3TB NAS drive. Right now it is CIFS protocol I use to 
connect to it. I have a problem playing mp3 files, watching movies and 
opening pictures stored on the NAS from FreeBSD machines. It goes black 
or does not start. On my ubuntu machines on the same system it functions 
flawless. So I guess I am missing something. Anyone have a clue ?

THX, Kenneth
