I currently have a nice tuner for my TV but it does not have any hdmi ports. I just upgraded to a new apple tv but have no way of hooking it up. I have heard of rgb to hdmi adapters. Do they work? Are they worth it? I hear there are problems because hdmi is digital and rgb is not. My second idea to hook the apple tv up to the tv with hdmi. The problem with that is I don't know how to play the video through the hdmi and the tv while also using the optical audio to through the tuner. Would that work?
