When I switch the HD-E1 (playing through HDMI to my plasma), the plasma flickers like mad until the HD-E1 has finished booting up and it is able to display either a SD or HD DVD. Once the machine is ready to display the menu etc, then the picture is fine. It is only from when the power button is displayed until the menu is displayed that I have an issue. In fact if I press the SETUP button on the HD-E1, nothing is displayed until a DVD had been loaded and I press stop. I am not sure if the problem is actually with the setting on the DVD or Plasma. It is a problem I guess I can live with but apart from being irritating; can this fast flickering cause a problem with the Plasma TV?
