I have direct tv, and i just bought a vizio hdtv. Playing games or watch blue-ray movies looks great. But when i watch tv, the picture is worse the my real old tv. I know, i know, buying an hdtv with out a upgrade from direct tv means i will have cable in hd. I just want to know, why the picture looks worse? And is there anyway i can clean up the picture with out upgrading? If it helps here is a link to my tv
