I'm getting ready to purchase hardware for a core and 1 media director, and I notice in the core hardware section the sentence "Further, it is best to have the TV card in the Core server". I am wondering why this is, because I intend the server to be in a closet, with no tv hooked to it. Is this because one may want to hook an OTA antenna to it, and record shows? This is the only reason I can think of for the card to be there. In my situation, I intend for one of the media directors to be capturing from my directv PVR, with an IR blaster to control it from another room. Anyone know why a tv card would be in the core?
