comunication between devices

[tyler785]

I'm a newbie with Linux MCE.  I installed with the dvd install for my core,  Then I hooked up my NAS and it detected that fine and added all the media.  I then used my old laptop to use as a thin client MD.  I booted it up via the network and the core sent the install and that went fine as well.  My question is, can I control the MD with the core or vice versa?  I'm using the interface U1 and when i click on location of the device in the lower right corner and pick the room that contains the other device, I don't see any media to play or anyways to control it.  Am I looking in the wrong spot or is there some sort of installation/configuration problems.  Thanks for any help or direction to a guide to explain this problem.
