This may be a dumb question; but, I am going to ask it anyway. Does anyone know the difference between Interlace and Progressive. When I connect my DVD player to my TV with S-Video and set the DVD to Progressive, the picture is fine. However, when I connect my DVD player to my TV using Component Video Cables, the picture deterioates badly until I switch my DVD from Progressive to Interlace. At that point, the picture shows up fine. Why is that? Also, when I use Component Video Cables from my DVD player to my receiver and run the Component Video Cables from my receiver to the TV, no picture appears. Would this be a problem with the receiver? I thinking that it may be because when I connect straight from the DVD to the TV the picture is fine. BTW, I have an old receiver. It's a Yamaha RX-V620. I do plan to upgrade to the RX-V1500 or the RX-V2500 within the next two months.
