WD TV LIve Plus - Defect - playing a YouTube playlist

If I select  playlist  from YouTube interface and  press Play button it display error message

“This video is restricted by the video content owener and it is not aviable on tv connected devices.”

Even though I am the owner of the content and has not defined any such restriction. 

If I browse the contents of the playlist and select a video to play… it works fine.

When you say that you are the content owner, do you mean that all of the videos in your playlist were created and uploaded by you?

Yes! I uploaded a couple of test clips, Added them to a playlist, tried to play the playlist  from WD TV Live Plus… and it could not.
