I just set up sharing from my iMac and then connected to the particular drive that I store my movies and TV on from my Macbook Pro. I have that connected to my tv in the living room.
I then just use FrontRow (place a shortcut from the netowrked drive in theM Movies folder in the home directory). Works great. Once in a while I get a glitch, but rare, and I am using mixed b-g router.
