Streaming DVDs and Blu-rays from my home theater computer

I am trying to stream Blu-ray and DVD movies I have ripped to my home theater computer to my WD TV  Live. I am running Windows 7 Ultimate on this computer on a gig network. The network is done with Cat6 cable and Cat6 patch cables. I am getting lagging on all video. I have the DVDs ripped as .vob and Blu-ray as .iso. Is what i want to do possible with the WD TV Live? If so how?
