I recently purchased a Denon DVD4800 and connected it to Samsung HD/DLP TV via a component video cable. When DVD is in progressive scan mode I get a distorted picture on the screen. It appears as one inch vertical lines. I have a good (not great) picture when not using progressive scan. Component video cable is a "Cobalt" and I assume high quality by the price I paid. Anyone have any thoughts on what could be causing this? Thanks in advance.
