Hello, My equipment is older and has only rca or s-video outputs. I have an LCD projector setup and it has an RCA and an S-video input. Instead of switching cables like I have been, I have routed all my video through my receiver which only has rca video in and out. I am wondering if there would be any difference in picture quality by using an rca to svideo cable and plugging into s-video on projector or just using a rca cable and plugging into rca input in projector? Since the original quality is going to be from rca in the first place would it matter? I also thought I read that it might still be better to use rca to svideo since the svideo input may have a higher resolution which may clean up the rca output from the receiver? Anyone shed some light?
