Resume watching a movie

I use to have older WD TV systems (had 1 in living room and 1 in bedroom) and I use to be able to stop a movie in one room and resume it in the other, via my internal LAN using the WD Livewire. I upgraded to the WDTV Live (again 1 in living room and 1 in bedroom) and I do not seem to be able to do that with this model. Does anyone have this issue or some advice on how to establish this feature? It really was quite useful.

Hello, where do you have your movies saved? 

I always keep all of my media files on a shared network drive.
