WDTV Live shows up on iTunes but not on Windows network

I am able to see my music (which is on an external hard disk attached to the WDTV) on iTunes under a Shared Folder named WDTVLIVE. But when I want to copy it onto my iPod and I go to “Add Floder” option in iTunes, WDTV does not show up in my Windows Network. I am using Windows 7. Can anyone suggest a solution?

Make sure you turn on SHARING on the WDTV Live’s network setup.
