Cant stream from My Book Live to Samsung Blu Ray (D5500)

Hi - im slowly going mad, i hope someone can help!

I have the my book live.  It is set for media sharing to all devices at my home. It contains a range of different media files including MP4, DivX, Avi’s, Mpeg’s. 

I have just bought a Samsung bd D5500.  i have enabled the wireless network on it through the dongle.  It detects the My book lives but when selected it shows no files.  So i cant play movies from my my book.

When i connect the sames files through a USB the Bluray has no issue playing them, so it has the capability to play the files. 

Is there something i can do to fix this?

If you have a lot of videos it might take a while for the media library to compile, but just in case you can go to the my book dashboard, settings, media, status and then rescan.
