Can't play to WD's media server

I am trying to play music and video to the WD TV Live hub media server via DLNA.   I am trying to play from a Android using  the DLNA app that came with the phone and I have tried IMediashare.

The phone is a Motorola Bionic.   What happens when I play a file I get “An error has occurred”  then when I look further it says “UPnP command error”.

I can get files to play from PC using Windows Media player.   But once I get the error nothing will play from anywhere until I reset the WD TV Live Hub.

Has anyone experienced this and what solutions are there?

The hub is connected by Ethernet.

You may take a look to this:  http://wdtvforum.com/main/index.php?topic=5495.0, it shows a list of compatible DLNA servers with the WD TV Live, it may also apply for the Hub.
