using hdmi or a hidef box? I have seen digital projectors hooked up to cable before, well actually I just watched tv on a digital projector, now I am planning to get a digital projector and I want to hook it up tothe cable in my room, but the problem is that I don't have hidef cable or a hdmi box, I can't afford the monthly cost of a box. I was hopping that it would be possible to hook it up through RCA or S-Video. I just want to hook up an F connection to a connection that fits that projector but not have to use a cable box that converts it into hidef. There must be a way because I know people have done it in the days where hdmi wasn't incorporated into the makeup of the digital projectors of today. If anyone knows anything please help I really need to make this happen.
