I'm considering purchasing a Sharp 9000 Front Projector to view HDTV and dvds. I'll be using an 84" screen. My question is this: Do I really need to purchase a separate video processor? The review in Home Theater (Jan. 2002) suggests that it may not be neccessary because the scaler in the Sharp is actually good. I'm not convinced that the cost of the processor really warrants it. I suppose I could buy it without a processor and see if I like it. Any thoughts? I'm also advised that even with a separate processor , if I use an HD satellitetuner the processor could not be hooked up so that non-HD channels would be processed. That is, it would only be used to enhance dvds. Does this sound right?
