Hey, you asked, and the answer just happens to be complex. But if you just want to get your TV into at least the right ball park, grab a THX certified DVD and see if it has an option in the menu to run the THX optimizer. It is a far cry from perfect, but it'll get you in the right direction on the cheap. Also, make sure your TV isn't set to overscan the picture (often a 16:9 mode isn't what you want, everyone calls it something different but look for something along the lines of 1:1, Full, or Just Scan, etc.), and turn off any and all motion compensation.
