I've posted this on the plasma forum and got no joy. Any one on here help me out? cheers I've been looking at an iscan ultra, so a few questions. How much differance would a scaler make to a pw7? Can sky go in via svideo and dvd go in to the scaler via component and come out via dvi? Will it improve sky+? Would s video from the sky+ into a scaler then out via dvi be better than sky+ into pw7 with a rgb to vga convertor? Would component from a 757i into a scaler and out via dvi be better than going into the pw7 via component direct from the 757? Any help most welcome.
