I just bought an expensive Sharp 32GD4U LCD, and I have it plugged into my Hugher TIVO receiving DirecTV. I'm shocked at the picture. It isn't as good as what I had on a $250 RCA tv that was there before? Right now I'm using an S-Video cable from the TIVO directly into the Video Monitor in on the Sharp. I'm not sure what I'm doing wrong, or what I should do to get a better picture?
