I'm looking at the MITS WT-46809 - perfect size, fits my budget, etc... The problem is that I watch a LOT of regular TV via DirecTV and TIVO and keep reading (here) that the expansion modes on the MITS sucks. So I'm thinking no problem, I'll just watch regular TV in the narrow format. But then I also heard that if I watch TV in the narrow format I risk burn-in. Then I've heard that burn-in is not a problem if you turn the contrast (or was it sharpness?) all the way down (where I'm told it belongs)(I'm told a lot, doncha think?). Thoughts?
