i have a rear projection Mitsubisti widescreen and will soon be looking for a new display device. Being a tube display, i (as stated in the manuual that accompanied the device) try to keep the screen filled. This means "expanding" television and older movies. i tend to think that my viewing time is 1 hour viewing widescreen material per 2 hrs of 4x3. i like older movies, etc. i am really tired of "expandind" older original material to avoid burn-in. When looking for a new display device, i would rather not do this. How should this effect my purchase of a plasma, LCD, etc? Any advice would be welcome. thanks!
