I have 2 WDTV Live Hubs in my home. When I connect to my server (12 tb RAID), it is very very slow to navigate through the various directories. This is through files, or via media seerver. When I connect to a different computer, the navigation is quick. Both computers and the WDTV are connected to my network via CAT 6. Connecting to the server from the other computer results in very quick access to the files. Only the 2 WDTV hubs are slow to update the file lists. They play the files without issue. Juts navigating between directories and listing of files is slow.
