My Cloud and Sony Bravia not working

Hi Everybody
I have just got My Cloud set up with my Mac and is it visible on my network.
Music and Videos all in place etc.
All ok with Desktop, iPads etc but my Sony Bravia cannot find the device when I use Video (the red one).
Am I correct in thinking I should be able to stream from the My Cloud to my Sony Bravia?

@Orty Do you have everything set up in the Dashboard? I have Windows instead of a Mac but my Sony Bravia works fine with my Sony TV and has for two years. See images below. Click on, tap or activate images to enlarge them. The XBR-75X850D is my Sony TV.

See Twonky too.
