Can't see files on My Book Live

I have just setup a My book Live and can access it via my Windows PC.

I can see the name of the device under Media servers on the Live hub, but when I select it as a content source all I get is a box saying “No Content Shared”.

I have copied video files to the My Book Live under the /public/shared videos folder.

What else do I need to do?

So, on the Hub, you do see the MBL as a SERVER under the “Network Shares” list?

… but if you select the MBL’s name, it says No Content?

…or is it that the MBL doesn’t appear in the list of servers?
