I’m having a problem with this message too.
I just traded my iPhone S4 with a Samsung Galaxy Note 2.
On my iPhone I used the app ‘iMediaShare’ to stream content to the WD Live Media Player and had no problems at all, now that I’ve switched to the my Note 2 and installed it there, I always get this message !
I’ve just tested it on my PS3 and the app works fine there, so it’s a WD software problem.
Please get this fixed WD !
