I have managed to purchase a second-hand projector (an ASK) more on a whim than desire for a home cinema. I'm currently projecting an image onto my living room wall using my PS2 as a DVD (and playing games) and running the sound through my stereo. I'm actually happy with the image quality (some DVD's appear better than others) but have a couple of queries. 1: Would using a stand alone DVD produce a better quality image (across a broad range of DVD's)? 2: What is the picture quality like generally if running straight out of Sky box into the PJ? 3: Does a screen (either DIY or purchased) make a huge difference to picture quality?
