Using Plex on my computer with WD TV Live

I was using my WD TV Live player to access Plex which I have installed on my Computer. This allowed me to to access my movies in external hard drived attached to the computer. This seemed fine until I added another external drive to the PC and now the WD TV player seems to be unable to play them. I can see the files but when I click play I just get the circle going round and round. Any ideas?

Hello, do the files on the first hard drive still play fine?

You should not need Plex to do this.  If you share the drive (or just some of it’s folders you want to access) with your network, the WD should pick it up via Network Shares, and you should be able to access and play your movies.  (Do not use Media Server to access ISO movies; media player will not work this way.)
