Latest media isn't syncing to other devices

I have always been able to see any media added to my “My Book Live” 2TB device after adding it to my public folder on devices such as my Samsung S2 (through WD Photos app) and my PS3 (through TWONKY).  In the last few weeks however, new media is not showing up on these devices.  Any suggestions as to what might have changed and how to rectify it???

Many thanks

Hello, 

You could try rebuilding the media server.

To access the Twonky server see the link bellow:

Thanks very much for the advice and link.  I will try this next.
