Since a few months I own a WD TV Live HD media player and I'm pretty satisfied with it. The performance is good and it's quite stable.
But from the beginning I had issues with the CIFS implementation of Solaris (and all the flavors of it) and the WD TV Live HD as a CIFS client. I simply can't access a share which is shared using the Kernel CIFS implementation of Solaris. I followed the official OpenSolaris CIFS guide so far but still no luck. See http://www.oracle.com/technetwork/java/opensolaris-nas-142265.html for details.
Has anybody experience using a ZFS/Solaris flavored NAS system and this client? I tried also the newest beta firmware of the WD Live TV HD and Solaris 11 Express which was released yesterday.
UPDATE: I solved the issue using the avahi zeroconf daemon to propagate the CIFS service to the client.
