I think my biggest culprit is the Noggin station. My son loves that station and since they don't have commercials, their stupid logo stays there all the time. I sat down with my wife today and showed her how to move the PIP over the logo. hopefully that will help.
This burn in thing really annoys me also. I told my wife she can not let my son watch Noggin anymore. Their logo stays the same all day long, and since there aren't any commercials its really bad. I know contacting the networks and the fcc is worthless.. but, I did contact Nielsen Media Research...
