I have a scientific atlanta 3250HD box from Rogers here in Canada. I have 2 of these hooked up to 2 different televisions. I am running both using a DVI to HDMI wire for the video. On both tvs, I am getting these vertial lines that are barely noticeable going up and down the screen. They are very noticeable when there is red being shown, but the lines are always there if you look closely. The lines are evenly spaced, and go across the entire screen, and run up and down. Does anyone know what this could be? THe lines don't seem to be there on high def channels, but are present on all the standard def channels. ANy ideas?
