Following advice from others on this forum I upgraded my lead from s-video to component input to join my Sony 735 to the Sanyo plv30. I was staggered at the difference. The chckenwire effect which previously was quite noticeable on scenes with snow or sky was eliminated. BUT - on a large number of my dvds, the picture judders up and down when using the component inputs. The problem disappears when I revert to s-video. Has anyone else had this problem ? Any ideas on what's causing it and how it can be put right ?
