Im toying with buying an Infocus projector.... probably the X1 or X2.... maybe at a severe push... an X3. The X1 is old but still of interest because it uses the Faroudja processor. Trouble is, I don't know what benefit this delivers. I've read that the X2 is cool as long as you use progressive scan sources... but what does that mean? I'd be looking to stick my PC through it and my consoles Xbox/ps2 through on S-video... Are these progressive or interlaced sources... Or am I getting this all wrong. Any expert guidance to unlock the mysteries of what progressive scan means to a buyer of these machines would be most appreciated.
