Can't browse music on media server

Have My WD TV Live Hub connected and a windows 7 PC acting as a media server.  I can see the server and browse/play videos no problem, but when I browse to music it says no files.  Other DLNA clients can see the music files - any thoughts on why the WD device can’t?

Just out of curiosity… should I try connecting to a network share instead of media server?  That might solve my problem with MKV movies with DTS sound tracks not playing as well.  I haven’t tried this.  But still curious why I can’t see music through the media server.
