I also have a 37" Panasonic Plasma and I use MP on it since I bought it. There are absolutely no burning effects at all. My wife (and sometimes me too) often lets the MP home screen on the screen for 1 or 2 hours. Once we forgot it for 6 hours. Effect: NOTHING. I think it´s important to have a quality screen (no discount screens), and lower the brightnes and contrast a lot. I set it to 30%, and that´s enough.
Also the logo burning effect while watching CNN can´t be true. I don´t know how it is on CNN, but if the is a commercial here in germany, the logo isn´t there. So there is max. 30 minutes for the logo to burn in before a commercial break, and that is not enough. But the 5 minutes break is enough to normalize this part of the screen.
