Hello, I am new to this forum and have some questions. This is kind of long so bear with me. I have just started to gather equipment for my theater and here is what I have so far: Sony VPH-1270 CRT Multiscan projector Extron Lancia line doubler cheap DVD player 70x70 screen The problem I had at first was getting a signal to the projector which only has S-video or RGBHV inputs. So I had to go with the S-video, but I know that isn't that great. So I looked around to find a way to get a better signal, or my signal converted, and nobody knew how. Then I got a hold of the custom installers at Magnolia HiFI and they told me Extron makes a signal converter, but it is too expensive. So I looked some more, and got the line doubler, which has the output I needed. My friend says that a line doubler isn't going to do anything to cable TV, so it was a waste of money, when I could get a progressive scan DVD player. But since I have no way to hook it up other than S-video, I still needed some kind of signal converter, so the line doubler works for that. So here's my real questions: 1. Is this setup going to give me the best, or close to the best picture I can get with my projector? 2. What about a scaler? I have read they can make the resolution higher to maximize the projector. But do they make the picture worse? I've heard about artifacts. 3. Does the line doubler really not do anything to cable? So football games are still going to look like crap? 4. and finally, are there enough things higher than 480p worth worrying about getting more resolution for? Someone told me there isn't anything that uses 1080 yet, so don't worry. Thanks for any help you guys may have, these may be newbie questions, but I didn't see the info I was looking for when I was searching around.
