Has anyone had any luck with reducing the screen door effect. I have a Sanyo PLV-70 LCD projector using component video input (hopefully to upgrade to DVI soon) displayed on a 108" diag. Dalite screen connected to HD DirecTV. I notice it mostly when watching CBS-HD. When I watch HDNet channel, I don't see any at all. So, I think it may be a function of the resolution of the transmitted signal, rather than the LCD projector. Does anyone have any insights about this phenomena? Thanks. Lew W.
